Our Products Digital Audio Video Broadcast Test MaxEye Technologies provides comprehensive solution in digital video audio broadcast test. We provide generation analysis functions in NI LabVIEW system design software, for generating analyzing the stard complaint signals for the following Digital Video/Audio Broadcasting (DVB/DAB) stards 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 stards.

3 The MaxEye Signal Generation Software is an ideal test tool for generating test signals with different configurations under different conditions. It can be used to completely test the receiver to characterize its performance during design, verification manufacturing. Our software supports multiple payload types TS, Audio files, Test Patterns,, Binary files PN Sequence. Coding, modulation other parameters of the toolkit can be easily configured using the LabVIEW API VIs. The toolkit also supports adding impairments like IQ impairments, frequency clock s 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

4 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 stards-based modulation accuracy, power measurements spectral measurements to help engineers evaluate, design manufacture transmitters, amplifiers, tuners, repeaters, modulators gap-fillers. Coding, modulation 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 validate the transmitter signal issues. The toolkit measurements can be used to calibrate the DVB transmitter. The EVM vs Subcarriers EVM vs Symbols enable the time frequency domain analysis of the transmitted signal to identify the issues in the transmitted signal. This toolkit provides SFN measurements with the power delay of each transmitter path. These measurements are ideal for SFN planning, maintenance, optimization.

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

8 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 measurement products, services turnkey solutions in signal processing communication engineering. For more information about our test measurement solutions for further information on MaxEye technologies kindly refer to 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".
