R&S FSH
Two-port measurements with the tracking generator

E-11
Connect the DUT between the tracking generator
output and the RF input. The R&S FSH displays the
magnitude of the transmission of the DUT.
Transmission measurement using the connected VSWR Bridge R&S FSH-Z3
Some measurement tasks require that both the transmission and the reflection be determined. To
eliminate having to repeatedly mount and dismount the VSWR bridge, the VSWR Bridge R&S FSH-Z3
(10 MHz to 6 GHz) includes a switch that bypasses the VSWR bridge and simultaneously switches the
tracking generator signal to the output (Gen Output) of the VSWR bridge. The switch is controlled via
the control cable, which is connected with the power sensor socket of the R&S FSH. Due to the
insertion loss of the VSWR bridge, the output level of the tracking generator is typically 4 dB lower. The
frequency-dependent insertion loss is compensated in the measurement after calibration.
