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".

About The LabVIEW Tools Network

NI Alliance Partners accelerate developer productivity by creating LabVIEW software add-ons

and apps that receive a Compatible with LabVIEW certification and are distributed through the
