Keysight FieldFox Microwave Spectrum Network Analyzers - to 50 GHz
FieldFox microwave spectrum analyzers provide industry-leading amplitude accuracy of ±0.5 dB at power-up, with no warm-up required, allowing field users to instantly and precisely characterize transmitter power. They can detect more signals in the band of interest with phase noise of -111 dBc/Hz at 10 kHz offset, and measure low-level signals in the presence of high-power transmitters with spur-free dynamic range of 105 dB.

FieldFox Handheld Microwave Analyzers now offer I/Q Analyzer mode
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 10Â MHz of analysis bandwidth and requires the spectrum analysis option (not supported on model N9912A).
