Keysight N9936A – FieldFox Microwave Spectrum Analyzer (14 GHz)

• Spectrum analysis frequency range: 100 kHz to 14 GHz
• Make accurate spectrum analyzer measurements (± 0.5 dB) without warmup
• Capture intermittent signals with 10 MHz gap-free, real-time bandwidth
• Carry one lightweight unit at 6.6 lbs

The Keysight N9936A is a Field Fox microwave spectrum analyzer with a frequency range of 100 kHz to 14 GHz. The standard model includes:

• 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, and satellite communications, and commercial microwave backhaul, you may be responsible not only for hardware installation and maintenance but also for over-the-air signal quality. You may also need to regularly monitor unexpected signals and perform signal surveillance.

FieldFox’s spectrum analyzer is optimized to 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 (-111 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.

For information on the other analyzer models in the Field Fox series, please see the selection information further below on this page.

Field Fox spectrum analyzers are easily customized to your specific application with over twenty software options. For detailed information regarding options, please view this document beginning on page 13.

Many models to choose from

The Keysight FieldFox series contains a large number of models, separated into two groups, the A series, and the B series.

Between the two series, there are over 40 FieldFox models to choose from. The documents below provide detailed information on both product capabilities, as well as available options for each. Each bullet in the list below will open a document in a new window. The FieldFox offers a variety of bandwidth ranges and is easily customizable to your specific application via software options.

Please note, that option part numbers are specific to each analyzer and can be viewed in the accessories section on the left side of their respective pages. For example, option 010 (vector network analysis) for N9912A and N9913A would be N9912A-010 and N9913A-010.
