2.2.2 Measuring the Vector Reflection
To perform vector measurements you have to equip the R&S FSH with firmware
application R&S FSH-K42.
Reflection measurements are available for all R&S FSH models with a tracking
generator and VSWR bridge.
With a model that features a VSWR bridge, you can perform the measurement at both
ports. For models without a VSWR bridge reflection measurement are possible only on
port 1.
► Press the MEAS key.
► Press the "Meas Mode" softkey.
► Select the "Vector" menu item.
The R&S FSH starts vector measurements.
► Press the FREQ key.
► Enter the frequency of the DUT.
► Press the SPAN key.
► Enter an appropriate span.
As you have changed the frequency settings, you should calibrate the R&S FSH for
more accurate results.
► Calibrate the R&S FSH for vector reflection measurements at the port you want
(see above).
► Reconnect the DUT.
The R&S FSH shows the magnitude of the reflection.
To evaluate the results, you can use, for example, markers. To get different aspects of
the results, you can use several measurement formats, like the phase or the reflection
coefficient.
► Press the "Meas Format" softkey.
► Select the format you would like to see.
The R&S FSH adjusts the display accordingly. The current measurement format is
always displayed in the status line.
