Interference Hunting with the Keysight FieldFox

Identify and locate the source of unwanted signals with real-time spectrum analysis.

FieldFox’s spectrum analyzer will excel in a dynamic spectral environment. You may face measurement challenges such as the need to detect a low-level signal under strong signal conditions (requiring high dynamic range), or close-in small interference signals (requiring excellent phase noise). FieldFox’s superior dynamic range (TOI +15 dBm), close in phase noise (-117 dBc/Hz at 10 kHz offset), and fast sweep time make these challenging tasks easier. FieldFox’s spectrum analyzer also provides a full power measurement suite and complete trace and state control.
