Both (HEAC and eARC) configuration need a power supply to supply the HEAC Fixture. The options available are:

• E3631A (Keysight E3631A Triple Output DC Power Supply)

• E363xA (Keysight E363xA Series Programmable DC Power Supplies)—default option

• E364xA (Keysight E364xA Single Output DC Power Supplies)

• N67xx (Keysight N67xx Modular System Power Supply)

eARC

By default, the Station Configurator is configured for HEAC Rx testing.

Select the eARC check box to configure for eARC Rx and eARC Tx testing.

Once the Station Configuration stage is complete, click Next.



Test Instrument Configuration

The Instrument Configuration stage of the Station Configurator is displayed. By default, the instrument configuration pertains to HEAC Rx testing, where you can establish connection to two 81150A (One connection to an Ethernet Generator and another to an Audio Generator). See Figure 4.

Figure 4 Instrument configuration window for HEAC testing



If you select the eARC check box in the Station Configuration stage, the Instrument Configuration stage facilitates connections to eARC instruments, such as 81160A and DSGA (BIT-3000). See Figure 5.

Figure 5 Instrument configuration window for eARC testing

After the installation process, all instruments are configured by default in Offline mode.

In the simulation mode, the hardware need not necessarily be physically connected to the test controller PC. The ValiFrame software cannot connect to any instrument in this mode. In order to control the instruments that are connected to the PC, the instrument address must be entered.

NOTEMake sure that all the selected instruments for the test station are connected to the test station PC controller by the remote control interfaces, such as LAN or USB. When starting a specific test station configuration for the first time, all instruments are set to the Offline mode. In this mode, the test automation software does not connect to any instrument. This mode can be used for demonstrations or checks only.



The address depends on the bus type used for the connection, for example, GPIB (General Purpose Interface BUS) or LAN (Local Area Network). Most of the instruments used in the HDMI ARC station require a VISA (Virtual Instrument System Architecture) connection. To determine the VISA address, run the Connection Expert (right-click the Keysight IO Control icon in the task bar and select the first entry Connection Expert). Copy the address string for each instrument from the Connection Expert entries and paste it as the instrument address in the Station Configurator window. Refer to “Using Keysight IO VISA Connection Expert” on page 20 for more information.

As mentioned earlier, the check boxes are clear and the status of each instrument is Offline. If you select one or more of these check boxes, a default address string appears for each selected entry. This address string is editable. You may either type or paste the correct address string, which you obtain from the Connection Expert. Click Check Connections to verify that the instruments are online and the connections for the instruments are established properly. If an erroneous instrument address configuration is performed, the Station Configurator displays a prompt to indicate so.

Once the configuration of the Instrument Configuration stage is complete, click Finish.

Next, you must launch the HDMI ARC ValiFrame (N5991) software to proceed with the configuration for HEAC / eARC testing. Refer to “Starting the HDMI ARC Station” on page 22 for more information.



Using Keysight IO VISA Connection Expert

Introduction

The Keysight Connection Expert is recommended to setup new connections or verify existing connections. Start the Connection Expert by right-clicking on the Keysight IO Libraries Suite icon in the task bar and selecting Connection Expert. A window similar to the one shown in Figure 6 is displayed.

Figure 6 Keysight Connection Expert

Under “Instruments”, click Rescan.



For each instrument that must be connected, verify that the corresponding information is listed on the menu to the left and that the VISA Address for each instrument shows a green tick.

Once all the instruments to be used are listed properly, their address strings can be entered in the Instrument Configuration stage of the Station Configurator (see Figure 4 and Figure 5). The recommended way of doing this is to copy and paste each instrument address as follows:

Click the “VISA Address” field next to an instrument in the Connection Expert and copy the address. Highlight the corresponding entry of that instrument in the Test Station Connection window, paste the address in the “Instrument Address” text field and click “Apply Address”. Repeat this procedure for all the instruments being used, except standard specific applications running on the oscilloscope.

The applications running on the Oscilloscope use a different technology to provide remote access to ValiFrame, called .NET Remoting Communication. The remote access is only possible using a LAN connection to the oscilloscope; therefore, only an IP address is used to connect to such an instrument.

Once all the instruments are set with the appropriate addresses, tick the check boxes for all such instruments, which shall be used by the Test Automation Software. This will set the instrument mode to “Online”. Click “Check Connections” to verify that the instrument addresses are valid.

Click “Finish” to save the changes and close the ValiFrame Configuration Wizard.



Starting the HDMI ARC Station

Start the ValiFrame HDMI ARC software by double-clicking “HDMI ARC Valiframe (N5991)” shortcut icon on the desktop as shown in Figure 7. Alternatively, click Start > BitifEye HDMI ARC N5991 > HDMI ARC ValiFrame (N5991).

The HDMI Audio Return Channel N5991 Valiframe window as shown in Figure 8. The ValiFrame N5991HE1A software connects automatically to the instruments, which are set to online mode in the Instrument Configuration stage (see Figure 4 and Figure 5). The application is ready for use once all the connections have been initialized successfully.



Figure 8 ValiFrame HDMI ARC user interface

The test parameters must be configured before running any test or calibration procedure. Click the NEW button to launch the Configure DUT window (Figure 9).



Configuring DUT

The Configure DUT window allows you to select Product (DUT) and test parameters, such as Product Type, test mode (either Compliance Mode or Expert Mode) and also all such Test parameters, which are related to the HEAC / eARC test configuration. These parameters shall be used later in several calibrations and test procedures.

HDMI ARC Parameters / 34



Introduction

All calibration and test procedures are included in the respective groups in a manner similar to how they are organized in the specifications.

Figure 10 HDMI ARC calibration and test window

The parameter grid on the right side of the window shows the parameters, which are related to the selected procedures.

The log list at the bottom of the window shows calibration and test status messages (regular progress updates as well as warnings and error messages).


Using the Software 3

To start one or more procedures, select the corresponding check box. The Start button is enabled and turns green in color. Click Start to run the selected procedures.

Once all the procedures are run, the N5991 configuration can be stored as a single ‘.vfp’ file using the Save button and recalled using the Load button without the need to configure the DUT again.

CAUTIONBefore executing the calibration or test procedures, ensure that the HDMI ARC Station Configuration is configured properly with all necessary instruments, such as the Infiniium oscilloscope set to “online”. All calibrations can be run in offline mode, that is, without any instrument connected. The offline mode is intended for product demonstrations with simulated data. CALIBRATIONS RUN IN OFFLINE MODE DO NOT GENERATE VALID CALIBRATION DATA.



Selecting, Modifying & Running Tests

Selecting Procedures

The calibration, receiver, and transmitter test procedure groups can be selected globally by selecting the check box at the top of the group. Alternatively, an individual test procedure can be selected by checking the corresponding check box. Click Start to run the selected test procedures.

Modifying Parameters

Most calibration and test procedures, as well as the groups containing them, have parameters that control the details of how the procedures are run. In Compliance mode, most of these parameters are ‘read-only’. In Expert mode, almost all the parameters can be modified. First, select a specific calibration or test procedure or one of the groups contained in the N5991 procedure tree, as shown in Figure 11. The parameters are displayed in a property list on the right side of the window. If not visible, click the Properties button for them to appear. The parameters are either listed alphabetically or in specific categories, depending on the selection on the left side. These parameters can be configured only before the selected procedure subgroup or procedure is started. All selected test parameters are listed in the MS Excel/HTML test results worksheets.



Figure 11 Modifying parameters

Running Procedures

To run the selected procedures, click the Start icon on the toolbar (see Figure 10). The procedures are run sequentially in the order shown in the procedure selection tree. Some procedures may require user intervention, such as changing cable connections or entering DUT parameters. The required action is prompted in pop-up dialog boxes prior to running the calibration/test procedures. To view the connection diagram, right-click the desired test or calibration. From the right-click menu, select Show Connection....



Results

Runtime Data Display

Most procedures generate data output. While the procedure is running, the data is displayed in a temporary MS Excel worksheet or HTML document (depending on the selected viewer in the ‘Station Configuration’), which opens automatically for each individual procedure.

Any MS-Excel worksheet or HTML documents, which are open during the procedure runs are closed automatically once the specific procedure is finished. As long as the N5991HE1A software is running, each result file (MS Excel worksheet or HTML Page) can be reopened by double-clicking the respective procedure. However, the individual files are lost when the N5991 main window is closed, unless you save the individual files or a collection of them.

Results Workbook

For your convenience, all individual results are summarized in an MS Excel workbook or HTML document at the end of the test run. All calibration and test data worksheets can be saved in a workbook by clicking the Export button on the toolbar of the HDMI ARC N5991HE1A Test Automation window. Keysight recommends performing this action at least once at the end of each N5991 procedure runs to avoid any data loss. If the calibration and test procedures are conducted several times during the same N5991 run, the resulting worksheets are combined in the workbook. If a test procedure is conducted without prior execution of calibration procedures in the same test run, only the test results will be saved to the workbook.

NOTEAs a safety feature, all calibration and test results are saved by default to the N5991 “Tmp” directory (C:\ProgramData\BitifEye\ValiframeK1\Tmp). The sub-folders contains the Excel files of the final results measured at each calibration and test procedure. In addition to the calibration data worksheets, calibration data files are generated. These files are saved by default to the N5991 calibrations folder. If these calibrations are run again, the data file is overwritten. To save the calibration data files at each configuration, the files must be copied from the directory: ‘C:\ ProgramData\BitifEye\ValiframeK1\HDMI ARC\Calibrations’ and saved manually in any folder before rerunning the calibrations.



Icon Representation

Once the selected procedures are run successfully, the icons that appear for individual procedures indicates the result (Pass / Fail / Incomplete) as described in Table 2.

Table 2 Icon Result description

Smiley Description

Indicates that the procedures have not run yet.

Indicates that the procedures are running.

Indicates that the selected procedures passed successfully in the previous run and the results are available.

Indicates that the selected procedures were passed in offline mode and the results are available.

Indicates that the selected procedures passed successfully in the current run.

Indicates that the procedure was not run completely in the previous run.

Indicates that the procedure could not be run in the present run. Most likely, the DUT failed during initialization, so no test was conducted.

Indicates that the procedure failed in the previous run.

Indicates that the procedure failed in the current run.



HDMI ARC Parameters

The HDMI ARC parameters are of three types:

• Sequencer Parameters

• Common Parameters

• Procedure Parameters

Sequencer Parameters

The Sequencer parameters control the flow of the test sequencer, not the behavior of individual procedures. They are identical across all versions of ValiFrame. One of them, Repetitions, is available for all procedures and groups in the procedure tree. The others are only available for procedures. Like all other parameters, the Sequencer parameters are shown on right side of the ValiFrame user interface and you may manually change them, as illustrated in Figure 12.

Figure 12 HDMI ARC Sequencer Parameters



All sequencer parameters are listed in alphabetical order in Table 3.

Table 3 HDMI ARC Sequencer Parameters

Common Parameters

The common parameters are used for several related calibration or test procedures. They are shown on the right side of the ValiFrame user interface when the selected entry of the procedure tree on the left is a group instead of an individual procedure.

The HDMI ARC Receiver Test Software has some group parameters (in addition to “Repetitions”) on the top-level entry of the HDMI ARC procedure tree. These are common for all Valiframe calibration and receiver test procedures respectively.

Procedure Parameters

The Procedure Parameters are all such parameters that are not part of any of the previously described categories. They are shown on the right side of the ValiFrame user interface when the selected entry of the procedure tree on the left is an individual procedure. Their purpose is to modify the behavior of that single procedure. Procedures often have parameters with the same name, but pre-configured settings always apply on the selected procedure, while their meaning may be slightly different.

Parameter Name Parameter Description

Procedure Error Case Behavior • “Proceed With Next Procedure”: If an error occurs in the current test or calibration procedure, continue by running the next procedure in the sequence.

• “Abort Sequence”: Abort further running of the sequence.

Procedure Failed Case Behavior • “Proceed With Next Procedure”: If the current test or calibration procedure fails, continue by running the next procedure in the sequence.

• “Abort Sequence”: Abort further running of the sequence.

Repetitions The number of times the group or procedure is going to be repeated. If the value is '0', it runs only once.

HEAC Calibrations / 38

eARC Calibrations / 49



HEAC Calibrations

Overview

The HEAC calibration procedures are performed by the software to calibrate the 81150A levels. The order of the procedures is mainly driven by the dependencies of the calibrations. Depending on the DUT configuration, calibrations are required to be performed. The results of each calibration are stored in the Calibration folder of ValiFrame, so that it can be used when running another calibration or test.


HDMI ARC Calibrations 4

Calibration Voltage Ethernet

Purpose and Method

The test fixtures and cabling attenuate the differential signal. To compensate for this, the differential signal levels of the Ethernet source are calibrated.

For this calibration, a differential Ethernet signal is generated at different swing voltage levels. For each step, the DSO measures the Histogram median value of the differential swing. The final measured value is saved in the calibration.

Connection Diagram

Figure 13 Connection Diagram for HEAC Calibration Voltage Ethernet

Parameters in Expert Mode

• Minimum Voltage: The minimum calibrated swing voltage.

• Maximum Voltage: The maximum calibrated swing voltage.

• Step Voltage: The value by which the swing voltage is decreased in the next step.



Result Description

Figure 14 Result for Calibration Voltage Ethernet



Figure 15 Result for Calibration Voltage Ethernet (contd.)

• Result: (Pass/Fail) PASS indicates that the calibration step succeeded.

• Set Voltage [mV]: The applied differential swing voltage for this step.

• Measured Voltage [mV]: The measured differential swing voltage for this step.



Calibration Transition Time Ethernet

Purpose and Method

The purpose of this procedure is to calibrate the transition time of the Ethernet Channel.

The test automation performs a sweep on the transition time of the Ethernet signal using linear steps. For each step, the Oscilloscope application is used to measure the top rise time, top fall time, bottom rise time and bottom fall time. Then, the corresponding transition time is calculated and saved in the calibration data.

Connection Diagram

Figure 16 Connection Diagram for HEAC Calibration Transition Time Ethernet




• Use mean value of all transition times: If set to ‘True’, the transition time is calculated as the average of the measured top/bottom rise/fall time. If set to ‘False’, the transition time is calculated as the measured top rise time.

• Minimum Transition Time: The minimum value of calibrated transition time.

• Maximum Transition Time: The maximum value of calibrated transition time.

• Step Size: The value by which the transition time is increased in the next step.



Result Description

Figure 17 Result for Calibration Transition Time Ethernet



Figure 18 Result for Calibration Transition Time Ethernet (contd.)


• Set Transition Time [ns]: The applied transition time for this step.

• Measured Transition Time [ns]: The measured transition time for this step.



Calibration Voltage Audio

Purpose and Method

The test fixtures and cabling attenuate the common mode signal. To compensate for this, the common mode signal levels of the Audio source are calibrated.

For this calibration, a Common Mode Audio signal is generated at different swing voltage levels. For each step, the DSO measures the Histogram for the most frequently value of the differential swing. The final measured value is saved in the calibration.

Connection Diagram

Figure 19 Connection Diagram for HEAC Calibration Voltage Audio




• Step Voltage: The value by which the swing voltage is decreased in the next step.



Result Description

Figure 20 Result for Calibration Voltage Audio



Figure 21 Result for Calibration Voltage Audio (contd.)


• Set Voltage [mV]: The applied differential swing voltage for this step.

• Measured Voltage [mV]: The measured differential swing voltage for this step.



eARC Calibrations

Overview

The calibration procedures are performed by the software to calibrate the 81160A and DSGA levels. The order of the procedures is mainly driven by the dependencies of the calibrations. Depending on the DUT configuration (Minimum and Maximum eARC Data Rate values), calibrations are required to be performed. The results of each calibration are stored in the Calibration folder of ValiFrame, so that it can be used when running another calibration or test.

Eye Height and Eye Width Calibrations are required for minimum and maximum eARC Data Rates as well.



Calibration Diff. Voltage

Purpose and Method

The test fixtures and cabling attenuate the differential signal. To compensate for this, the differential signal levels are calibrated by connecting an HEAC fixture to the eARC setup and measuring the differential swing with a DSO.

For the calibration, a differential eARC signal is generated at different swing voltage levels. For each step, the DSO measures the Histogram for the most frequently attained value of the differential swing for zero bit and one bit. The average value of zero and one bits is the final measured value used during the eARC differential signal testing. This calibration is done for minimum (4.096 MHz) and maximum (98.304 MHz) eARC data rate.

Calibration Cm. Voltage

Purpose and Method

The test fixtures and cabling attenuate the common mode signal. To compensate for this, the common mode signal levels are calibrated by connecting an HEAC fixture to the eARC setup and measuring the common mode swing with a DSO.

For the calibration, a common mode eARC signal is generated at different swing voltage levels using a DSGA. For each step, the DSO measures the Histogram for the most frequently attained value of the common mode swing. As per the eARC specification, the data rate for common mode voltage calibration is fixed at 2Mbps.

Eye Height and Width Calibration

Purpose and Method

There are two conditions to perform Eye Height and Width Calibration. At each condition the calibrations will be performed for both max and min eARC data rates.

The reason for two conditions is because in case both Eye height and eye width target values cannot be met simultaneously, which may happen as differential signal rise/fall times are slow at TP1. In that case, condition 1 requires the vertical eye opening 100mV should be met even though there is less jitter than 0.3UI. Vice versa, condition 2 requires the horizontal opening 0.3UI is met even though vertical opening is larger than 100mV.

Condition 1

1 Eye Height Calibration:

This procedure calibrates the eye height by measuring the vertical eye opening with a DSO using histogram method. It sends a signal with nominal differential voltage (400mV) and decreases the amplitude until the measured eye height is 100mV. The calibration is performed without injecting any sinusoidal jitter

2 Eye Width Calibration:

This procedure calibrates the eye width by measuring the horizontal eye opening with a DSO using histogram method. The differential voltage is set accordingly to get the target eye height by using the Eye Height Calibration. Then the sinusoidal jitter is injected and increased until the measured Eye Width is 300mUI.

Condition 2

1 Eye Width Calibration:

This procedure calibrates the eye height by measuring the vertical eye opening with a DSO using histogram method. It sends a signal with nominal differential voltage (400mV) and decreases the amplitude until the measured eye height is 100mV. The calibration is performed without injecting any sinusoidal jitter

2 Eye Height Calibration:

This procedure calibrates the eye width by measuring the horizontal eye opening with a DSO using histogram method. The differential voltage is set accordingly to get the target eye height by using the Eye Height Calibration. Then the sinusoidal jitter is injected and increased until the measured Eye Width is 300mUI.

HEACT 5-16 Differential Signal Receiver Performance Test

Purpose and Method

The purpose of this test is to confirm that the differential signal receiver of the HEAC Source/Sink DUT performs correctly within the clock frequency deviation and the amplitude deviation. This test also confirms the common mode disturbance and the tolerance for output impedance variation of the signal source.

The test is separated in different procedures depending on the parameter tested:

• High Level Voltage: The high level amplitude is set to two different levels: 0.2V ± 10%.

• Low Level Voltage: The low level amplitude is set to two different levels: 0.2V ± 10%.

• Clock Frequency Variation: The clock frequency is configured with two different deviations: 125MHz ± 0.005%.

• Common Mode Signal Disturbance: Common mode signal is set to 0.4V ± 20%.

• Impedance 110 Ohms: The data generator sends the signal with an output impedance of 110 Ohms.

• Impedance 90 Ohms: The data generator sends the signal with an output impedance of 90 Ohms.

• Cable degradation: The signal is sent with the worst cable degradation.

For each procedure, it is necessary to activate the HEC transmission on the HEAC Source/Sink DUT. After the required waveform is generated, the DUT signal is captured and decoded. If the correct Ethernet packed data is received, it indicates that the test has passed, otherwise the test is considered as failed.

As soon as the trigger level is found, the Valiframe software triggers the HDMI Application on the Oscilloscope. The Oscilloscope’s HDMI Application measures the Common Mode Rise/Fall Time on the Heartbeat pulse from the DUT. If ‘eARC Discovery’ is successful and the measurement performed by Oscilloscope’s HDMI Application passes, it indicates that the test has passed, otherwise the test is considered as failed.
