•Single Shot

•Continuous

•Sweep (one or two imbricated levels)

Simple InterfaceEMA Overview


Agenda



•ZIP is an open standard, lot of tools are available to work with

•All needed files for complete system definition may be merged inone unit

•Any usual manipulation regarding a complete systemconfiguration (copy, paste, delete) is as simple as any filemanipulation

•Debugging, checking, linking with other application, ... is easierthan any other proprietary design

Xxx.bky-ciz uses ZIP standardized format

Instrument Configuration concept & usage


Xxx.bky-ciz means « Instrument-Group »

As long as possible, filesare using ASCII-Textcoding.

Generic File « bky-igt » andSpecific File « bky-ist » are .INIfiles.

Instrument Configuration concept & usage


Opening a « bky-ciz » file

User will easily :

•Change some parameters

•Download/Upload one instrumentconfiguration

•Download/Upload all instrumentconfiguration at once

•Directly acts with one instrumentfunction from toolbar

Any bky-ciz file contains :

•One « Journal » tab

•As many tabs as available instruments

•ToolTips may help to know each button function.

•An html contextual help (F1) is available fromanywhere.

Simple InterfaceInstrument Configuration concept & usage


Instrument tab content comes from metaconfiguration file

[_MetaConfig]_PublicSections=['SINUS', 'RAMP', 'PULSE','DC','Trig', 'DacGeneric', 'DigitalOut', 'DeskewCheck','Mrk'][Sinus]_Label = 'Sinus Function'_DisplayCondition="mode == 'SINUS'"_PublicItems=[ 'SamplingFrequency', 'SignalFrequency', 'DbFullScale','OffsetPercent', 'Priority']SamplingFrequency=['Float', 'Sampling Frequency', 'Hz','DAC sampling frequency in Hz'] # 100E6SignalFrequency=['Float', 'Signal Frequency','Hz','Out Frequency of required signal in Hz'] # 1E6DbFullScale=['Integer', 'Amplitude','dBFS','Signal amplitude in dB Full Scale (dBFS) ex:0=>FS, - 6=>1/2FS'] #-6OffsetPercent=['Integer', 'Offset Value','%FS','Offset Value in % of Full Scale between 0 and 100'] #50Priority=['String','Priority to','','SIGNAL/SAMPLING'] # SIGNAL

Each instrument has one generic metaconfiguration filedefining what must be available to user.

Main purpose is to get « simple » usage reduced to onlyneeded parameters. There are two public/private levels :sub-tabs and parameters.

Even, there may be specific metaconfiguration file depending upon some « not standard »presentation. It means bky-ciz can be « customized » to best usage upon user needs.

Simple InterfaceInstrument Configuration concept & usage


Agenda



•Invoked reasons about “bky-ciz” are still valid here

•Even there are two new items :

•There are more needed files to enable complete description(“bky-ciz” is only a sub-set of what needed here)

•Results may use lot of files (depending upon execution mode :single, continuous, sweep)

Xxx.bky-muz also uses ZIP standardized format

Measurement Procedure concept & usage


Xxx.bky-muz : Configuration, Measurement, Results

•Configuration looks like what ’s inside bky-ciz (about instruments)

•Measurement is dedicated to the specific procedure to execute

•Results are made with measurements coming from execution ofprocedure « Measurement »



Xxx.bky-muz : the Measurement part

For « Measurement » (bky-muz), files bky-mgt & bky-mst are similar to bky-igt &bky-ist for « Instrument »(bky-ciz)



Xxx.bky-muz : the Results partThere may be more than only oneset of result files depending uponexecution mode.



Opening a « bky-muz » fileSimple Interface

User will easily :•Look at results, journal, configuration•Edit some instrument parameters or execution parameters•Launch measurement•Export results

« bky-muz » tabs are :

•Journal

•Execution

•Results

•Instruments (one for each unit involvedfor the measurement procedure)



Simple Interface

« bky-muz » file, the execution tab

Available sweep choices are coming frommetaconfiguration file too :

_SweepItems=[‘ VOLT ’]

_Sweep_VOLT=[‘ Y Voltage ’,2.5,3.5,.1]

Here is another choice comingfrom another instrument device(with differentmetaconfiguration).

Here is execution tab with Continuous mode selected. Note the icon used tolaunch the measurement procedure.

Error and Warningmessage window

All informationmessage window

shown inchronological

order (containsalso Error and

Warning).

“Last message” line

available from any tab



« bky-muz » file, the Results tab

For results also, display depends upon metaconfiguration file :[_Metaconfig]

...

_ResultsModule=‘bktm.rgeneric’

Aside « generic » presentation, there may be « specific » onesdedicated to known measurement procedures :

[_Metaconfig]

...

_ResultsModule=‘bktm.linearity’

Simple InterfaceMeasurement Procedure concept & usage


« bky-muz » file, integrated Results display

•Viewable from inside the same application wheremeasurement may be launched and parameters adjusted.

•Optimized display to each procedure.

•Fully integrated (sweep, ...).

Simple InterfaceMeasurement Procedure concept & usage


« bky-muz » file, exporting Results

•Export from :

•Simple Interface

•Windows Explorer

•One file at a time

•A full sub-tree at a time

•To :

•MS/Excel

Agenda



MS/Excel exported Results

Full traceability is still available through different sheet of same file, from measurementparameters, direct readings, corrected results, ... as needed for each specific procedure

Exported results & Report generation


Here is an example of whatcan be constructed usingMS/Excel functionality fromexported results files.

Main usage are table andgraphic display fromnumeric results.

However, graphic files (likescope screen shot, ...),graphic drawing (timingdiagrams, ...), and textualinformation may be merged.Such a full report looks likemanufacturer data-sheet.

Exported files +report file(s)

Exported results file names are predictable

Report file is to be linked with exported results

Inside Report sheet, data from exported files are usedto construct graphic, or table, or even to buildcomprehensive legend.


Traceability from final Report

Even from final report, user hasstill the ability to return tomeasurement at a mouse click!

HyperLink functionalityenables direct « bky-muz »‘insertion’.

It means, the user can checkhow measurement procedurewas executed to get displayedresult. Of course, it also enablesto execute a new measurementand ’see’ real-time resultscomputation.



Agenda
