IQ Streaming with Anritsu’s Field Master Pro Real-Time Spectrum Analyzer

September 24, 2021

In a world of increasingly sophisticated wireless signals competing in the available spectrum, the ability to capture and analyze those signals is in greater demand than ever. Interference — both unintentional and nefarious — threatens the fidelity of communications systems in high frequency (HF) and all the way up to millimeter-wave (mmWave) frequencies. With the Field Master Pro™ MS2090A Real-Time Spectrum Analyzer, Anritsu is now opening new doors for signal capture and analysis out in the field that have previously been restricted to the lab.

The Field Master Pro offers premium performance in three critical areas for spectrum intelligence:

  1. Frequency Coverage: with full coverage up to 54 GHz, there are no gaps where signals can be missed.
  2. Bandwidth: 110 MHz of capture bandwidth means more information across more spectrum.
  3. Real-Time Performance: with a minimum detectable signal of 5 ns, even the shortest duration signals cannot hide from detection.

The Field Master Pro combines these key features to offer comprehensive options for IQ data capture and streaming. Analysis of IQ data has become the most important tool in the signal analysis tool box. Using standard software applications, every detail of an RF signal can be analyzed and categorized. The Field Master Pro provides a unique combination of high RF performance in a field portable spectrum analyzer that can stream wide bandwidths of IQ data continuously. This application note will describe the Field Master Pro IQ streaming options and how to set them up to optimize for any application. Once IQ data has been recorded, it can be post processed in a number of PC applications including MATLAB, X-COM Spectro-X, and Anritsu MX280005A Vector Signal Analysis software.
