This feature allows for rapid diagnostics and characterization of cables, filters, and amplifiers. When combined with a directional coupler, it can measure impedance and characterize antenna VSWR.

Some parameters can be easily configured by screen touch with yellow areas in picture above.

Average

Total number of sweeps to average samples, larger numbers improve noise rejection

Start

Stop

Stop frequency sweep

Steps

Tracking SNA steps. The more steps you use, the longer the sweep will take. Recommended values are from 50 to 200 steps for a good compromise of speed and resolution.

Standard SNA requirement to rule out any cable, connector or environmental imperfection. The application will properly measure the response of your setup and will consider that 0dB response in order to refer any measurement to it.

Perform/Finalize SNA for continuous tracking sweep. Screen will be updated with SNA results every few seconds.
