FieldFox Handheld Microwave Signal Analyzer (44 GHz)
The Keysight N9961B is a FieldFox handheld signal analyzer. The standard model has a frequency range of 9 kHz – 44 GHz (useable to 5 kHz) and the following functionalities:
- Basic spectrum analysis, four traces, different detector types, radio standard selection, limit lines
- Channel power, occupied bandwidth, adjacent channel power, spectrum emission mask
- AM/FM tune and listen, field strength measurements, antenna factors, frequency counter marker
In microwave, radar, satellite communications, and commercial microwave backhaul, you may be responsible for hardware installation and maintenance as well as over-the-air signal quality. This could require regular monitoring for unexpected signals and performing signal surveillance.
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.
