RF Explorer Pro Tracking SNA mode

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.

Notes
Sweep navigation control is not available for replaying sweeps

RealTime and Average are the only available traces

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.

Normalize

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.
