 Keysight (Agilent) N9925A FieldFox Vector Network Analyzer  

Keysight Technologies N9925A FieldFox Vector Network Analyzer brings bench-level accuracy into the field by delivering precise handheld RF and microwave measurements that agree with benchtop analyzers. It  can be configured with 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.

The FieldFox's four independent, sensitive receivers provide 94 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 wellrespected Keysight ENA and PNA network analyzers. FieldFox leverages Keysight microwave expertise to deliver consistent measurements with Keysight benchtop VNAs.  With the FieldFox N9925A, you can measure the common- and differential-mode reflections of a device. Mixed-mode S-parameters are also known as balanced measurements. This measurement requires the full 2-port VNA and 2-port cal functionality.
