The base FieldFox RF VNA provides transmission/reflection (T/R) measurements, or S11 and S21, with magnitude and phase.

Adding Option 122 (full 2-port S-parameters) brings new levels of accuracy and convenience for testing RF components. A full 2-port network analyzer lets you measure the forward and reverse characteristics of your components without having to disconnect, turn around, and reconnect them to the analyzer.

It also provides full 2-port calibration to give you the best measurement accuracy possible. Depending upon your application, you can choose the optimum performance level of an S-parameter analyzer (Option 122) or transmission reflection analyzer (base model).

You also can simultaneously measure and view all four S-parameters, with a single connection. FieldFox VNA contains four independent, sensitive receivers. The receivers provide more than 100 dB of dynamic range for vector measurements of high rejection, narrowband devices such RF filters. The receivers also make possible full 2-port error correction with the Unknown Thru method, allowing you to measure non-insertable devices.
