Spectrum measurements with the VSWR Bridge R&S FSH-Z3 or R&S FSH-Z2
connected
To localize interfering signals that can affect the reflection measurement on an antenna, for example, it
is useful to switch to the spectrum display. To eliminate having to dismount the VSWR bridge each
time, a typical value for the insertion loss of the VSWR bridge is incorporated in the measurement. This
corrective step requires that the control cable for detecting the bridge be connected to the R&S FSH.
Since the value is merely a typical frequency-independent correction value, an additional level
measurement uncertainty of max. 2 dB must be anticipated.
Operation:
Press the MEAS key.
Select the MEASURE softkey.
Select ANALYZER from the menu by using the
rotary knob or the cursor keys.
As soon as the control cable has been connected to
the R&S FSH, the VSWR Bridge R&S FSH-Z3 or R&S
FSH-Z2 is automatically detected and indicated both
on the display and the status menu. Automatic
detection requires that this feature be activated in the
SETUP menu (default setting).
