Test and Measurement software applications

This section of the page covers PC based software applications. These applications do not need any instrument for generation and analysis. It works offline. Generator application generates offline IQ data based on configuration made by the user. This generated IQ data later if required can be played using vector signal generator and emulated real time waveform can be generated for test purpose. Analyzer application analyzes already acquired realtime IQ data or offline generated IQ data. Different standard based applications are available in one single package and can also be licensed individually from developers based on need. The popular standards include WLAN, WiMAX, Zigbee, bluetooth, GSM, LTE etc.

Conformance Testing

Conformance testing is becoming more challenging with the introduction of advanced features in next generation wireless devices. Following are the tests carried out typically for wimax,gsm,gprs,wcdma,lte,td-scdma devices to comply for conformance specifications.
