VSWR

Description
►
The Voltage Standing Wave Ratio is the voltage ratio between transmitted and
reflected waves, usually measured in RF electrical transmission systems. The
VSWR function will use the Tracking Generator of the AE-166/167 as
reference signal.
Operation
►
Before starting a VSWR measurement, the tracking generator must be
turned on and normalized. If the TG has not been turned on and
normalized, the VSWR function will not be available.
Connect the TG output directly to the RF input.
Press
generator to on.
Press Normalize[F6] > Exe. Norm[F1] to perform a normalization.
Using a Return Loss Bridge, connect the DUT to the TG output and the RF
input of the AE-166/167 as shown in the below diagram.
Press
Press [F2] to turn the selected marker on.
Press Function[F5] > VSWR[F3] to turn the VSWR measurement on.
