Keysight N9936A FieldFox Microwave Spectrum Analyzer

Agilent N9936A Microwave Spectrum Analyzers

Carry Precision with You
Measuring up and earning a spot in your field kit is the driving idea behind Keysight’s FieldFox handheld analyzers. They’re equipped to handle routine maintenance, in-depth troubleshooting and anything in between. Better yet, FieldFox delivers precise microwave and millimeter-wave measurements - wherever you need to go.

Why choose FieldFox?

• Measure with confidence - precise measurements agree with benchtop results
• Withstands your toughest working environments - rugged enough to meet MIL-specs
• Weighs less than alternative solutions - 7.1 lb (3.2 kg)

 Leverage Our Legacy of Measurement Leadership
With FieldFox, you’re carrying the precision of our industry-standard benchtop analyzers. By delivering levels of consistency not available in any other handhelds, FieldFox ensures confidence in your results.

Inside, we leveraged well-tested algorithms from Keysight’s high- performance VNAs. To lighten your load, we simplified calibration by adding built-in standards and eliminating the need to carry calibration kits.

To enhance spectrum analysis, FieldFox includes the same PowerSuite measurements used in Keysight signal analyzers, enabling fast, accurate, one- button characterization of channelized communication systems. The InstAlign capability lets you instantly make accurate power measurements in the field, even when temperature fluctuates.

Spectrum Analyzer

In microwave, radar, and satellite communications, and commercial microwave backhaul, you may be responsible not only for hardware installation and maintenance, but also overthe-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.

Unprecedented amplitude accuracy without instrument warm-up

With FieldFox’s InstAlign capability, internal amplitude alignments occur automatically as environmental conditions change, without any user intervention. This provides unprecedented amplitude accuracy of ± 0.5 dB for spectrum analysis and power measurements. Better yet, FieldFox provides this accuracy immediately upon instrument turn on - no warm-up required.

Spectrum analyzer time gating

The testing of RF pulses is always challenging because so many instrument settings interact. With Option 238, gated FFT with time gating, FieldFox behaves like a spectrum analyzer and an oscilloscope. This enables you to quickly detect pulses in the time and frequency domains. A gate time of 6 µs to 1.8 s enables simultaneous examination of one or more pulses, or pulse rise and fall times, revealing the effects of spectrum growth due to various pulse shapes. Functions such as video trigger, external trigger and RF burst ensure reliable pulse detection. Automatic trigger-delay and bandwidth settings enhance characterization of RF pulses.
