FieldFox with I/Q Analyzer Mode (Opt. 351)

IQ Analysis is the ideal capturing tool to verify final signal chain integration or troubleshoot signal quality degradation due to hardware or software issues. The FieldFox I/Q analyzer mode (Option 351) provides frequency and time domain measurements and customizable multi-domain display views. I/Q data can also be captured on the instrument and analyzed using 89600 VSA Software, MATLAB, Python tool kit and other third party demodulation software. Additionally, I/Q capture data of an RF signal environment can be re-generated and played back using a vector signal generator. FieldFox I/Q Analyzer mode supports 10 MHz of analysis bandwidth and requires the spectrum analysis option (not supported on model N9912A). I/Q capture data file types include CSV, text (TXT), SDF (compatible with 89600 VSA Software) and MATLAB (MAT). Available on FieldFox models N9913/14/15/16/17/18A, N9935/36/37/38A, N995xA, N996xA.
