Digital Audio and Video Broadcast Test
MaxEye Technologies provides comprehensive solution in digital video and audio
broadcast test. We provide generation and analysis functions in NI LabVIEW system
design software, for generating and analyzing the standard complaint signals for the
following Digital Video/Audio Broadcasting (DVB/DAB) standards
AM+
FM/RDS/TMC+ DAB/DAB+/T-DMB
DVB-T
DVB-T2 DRM/DRM Plus+
DVB-S CMMB ISDB-T/Tb+
DVB-S2
DTMB+
DVB-C
ATSC /ATSC-M/H+
+ At present, analysis functions are supported only for these standards.
The MaxEye Signal Generation Software is an ideal test tool for generating test
signals with different configurations and under different conditions. It can be used to
completely test the receiver to characterize its performance during design, verification
and manufacturing. Our software supports multiple payload types – MPEG TS, Audio
files, Test Patterns, User Defined Bits, Binary files and PN Sequence. Coding, modulation
and other parameters of the toolkit can be easily configured using the LabVIEW API VIs.
The toolkit also supports adding impairments like AWGN, IQ impairments, frequency
and clock offsets to stress the receiver under real world conditions. The receiver’s
performance can be verified through BER analysis at various stages
MaxEye Signal Generation Software
NI PXI RF Platform
The MaxEye Digital Video Analysis toolkit is an ideal tool for analyzing the
signal quality of the transmitted signal. The toolkit measurements can be used to
calibrate the Digital Video Transmitter components. It provides standards-based
modulation accuracy, power measurements and spectral measurements to help
engineers evaluate, design and manufacture transmitters, amplifiers, tuners, repeaters,
modulators and gap-fillers. Coding, modulation and other parameters of the toolkit can
be easily configured using the LabVIEW API VI’’s that are provided with our software to
analyze custom waveform for specific test requirements.
MaxEye Signal Analysis Software
MaxEye analysis toolkit provides various measurement traces to enable the engineers
to analyze, troubleshoot and validate the transmitter signal issues. The toolkit
measurements can be used to calibrate the DVB transmitter. The EVM vs Subcarriers
and EVM vs Symbols enable the time and frequency domain analysis of the transmitted
signal to identify the issues in the transmitted signal. This toolkit provides SFN
measurements with the power and delay of each transmitter path. These
measurements are ideal for SFN planning, maintenance, and optimization.

MaxEye ZigBee Measurement Suite
ZigBee and the underlying IEEE 802.15.4 standard promise to give the market a cost-
effective standard-based wireless network that supports low data rates, low power
consumption, security, and reliability. MaxEye Technologies provides the signal
generation and analysis tools using National Instruments Vector Signal
Generators/Analyzers or Vector Signal Transceiver to test the physical layer and RF
front end of the ZigBee devices.
The ZigBee measurement suite supports generating and analyzing the signal as per the
IEEE 802.15.4 standard MAC and PHY protocol. The MAC and PHY layer parameters can
be configured using the LabVIEW API VIs.
i. OQPSK Physical Layer (2.4GHz)
ii. BPSK Physical Layer (868/915 MHz)
The standard defines different modulation types, data rates based on the frequency band.

About MaxEye Technologies
MaxEye Technologies founded in 2011, is a privately held company based in Bangalore, India;
with a vision to become leader in providing automotive infotainment test solution, RF test and
measurement products, services and turnkey solutions in signal processing and communication
engineering. For more information about our test and measurement solutions and for further
information on MaxEye technologies kindly refer to www.maxeyetech.com. Our products are
also available through LabVIEW Tools Network.
The name "MaxEye" comes from Communication Engineering. Our logo symbolizes the Eye
Diagram. The Eye Diagram is a Signal display pattern in which the digital signal in the receiver is
repetitively sampled. The signal is plotted every symbol period or multiples of the same. The
pattern is so called because it appears like a series of eyes between two parallel rails. This pattern
is usually used to diagnose the timing synchronization in a digital receiver. An open eye pattern
corresponds to minimal signal distortion or in other words can conclude a near perfect time
synchronization. A clear open eye pattern is also called "MaxEye".
