Keysight N9935A FieldFox Handheld RF Analyzer with 9 GHz Maximum Frequency and 10 MHz Gap-Free Bandwidth in Lightweight 3.0 kg Design

Keysight's FieldFox handheld spectrum analyzers are equipped to handle your toughest working environments during routine maintenance, in-depth troubleshooting, and anything in between. Choose the Keysight FieldFox configuration that best meets your needs.

• Make accurate spectrum analyzer measurements (± 0.5 dB) without warmup
• Carry one lightweight unit at 3.0 kg (6.6 lb)
• Perform over-the-air measurements for 5G TF and LTE
• Characterize radar pulse profiles with a portable solution
• Use GPS/GNSS for geolocation and timestamping
• Capture I/Q data for RF signal monitoring and analysis
• Capture intermittent signals with 10 MHz gap-free, real-time bandwidth

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.

FieldFox includes options for VNA transmission/reflection (T/R) capability for S11 and S21 measurements, or with full 2-port capability for measurements of all four S-parameters and full 2-port calibration. With a full 2-port network analyzer, you can measure the forward and reverse characteristics of your component without having to disconnect, turn around, and reconnect it to the analyzer.

Additionally, the full 2-port calibration gives you the best measurement accuracy possible. FieldFox's four independent, sensitive receivers provide 117 dB of dynamic range for measurement of high rejection, narrowband devices such as cavity filters. The receivers also enable full 2-port error correction with the unknown thru method, allowing users to measure non-insertable devices accurately and easily.

FieldFox's calibration engine is the same engine that powers the well-respected Keysight ENA and PNA network analyzers. FieldFox leverages Keysight microwave expertise to deliver consistent measurements with Keysight benchtop VNAs.
