R&S FSH Network Analyzer Mode
Performing Vector Measurements (R&S FSH-K42)
Operating Manual 1309.6275.12 - 14 133
4.3.1 Measuring the Transmission
The example included here is based on a transmission measurement of a two-port
filter. The filter works in the frequency from of 1920 MHz to 1980 MHz.
Test setup
M Connect the input of the DUT to the tracking generator output (port 2).
M Connect the output of the DUT to the RF input (port 1).
Preset the R&S FSH
Before starting the measurement procedure, preset the R&S FSH to restore the default

M Press the "Result Display" softkey.
M Select the "Transmission Fwd (Port 1 2)" menu item for transmission
measurements in forward direction or "Transmission Rev (Port 1 2)" menu item
for transmission measurements in reverse direction.
Define the frequency parameters
Before calibrating the measurement, you should define the frequency parameters to
avoid interpolation of the results.
M Press the FREQ key.
The R&S FSH opens an input field to set the center frequency.
M Enter a frequency of 1950 MHz.
M Press the SPAN key.
The R&S FSH opens an input field to define the span.
