FieldFox RF analyzer can be configured with VNA transmission/reflection (T/R) capability for S11 and S21 measurements.

S11, S11 phase, Smith chart, and polar display are available with Option 303 (network analysis capability). To obtain S21 or insertion loss/gain, users need to order Option 110 (transmission measurement) and Option 303.

For in-fixture measurements, use FieldFox’s port extension or electrical delay capability to easily extend the reference plane to the device interface to provide accurate measurements. You can use the electrical delay capability to measure deviation from the linear phase by removing the linear portion of the phase delay.
