Find peaks

Transmission & filters

Remove cable delay

Moves the reference plane through an ideal, lossless line. Original data stays saved.

Remove cable or adapter from S11

Port 1 faces the VNA; port 2 faces the antenna.

Cable distance & time domain

Keep a distance range

Keeps reflections in this range with tapered edges. Sweep bandwidth limits separation; original data stays saved.

Measurement details

No measurement yet.

Calibrate at the cable end

Use ideal OPEN, SHORT and 50 Ω LOAD standards.
Transmission calibration

Connect a THROUGH between both ports. For ISOLATION, terminate both ports with 50 Ω loads.

Calibration standard models

Use the values supplied with your standards. Zero gives ideal OPEN and SHORT.

Higher order coefficients
