R&S FSH Measurements using the power sensor
1309.6275.12 4.73 E-2
Operating sequence:
Press the MODE key.
Press the POWER METER softkey.
The Power Meter submenu opens.
The R&S FSH opens the screen for power measurements. If no power sensor is connected, no
measured value is displayed. If a power sensor is connected, the R&S FSH sets up a connection via its
interface and after a few seconds displays the measured power.
In the event of incorrect operation or sensor malfunction, the R&S FSH outputs the following error
messages:
Message Cause Remedy
Error in zeroing: signal at
sensor
A signal was present at the
power sensor when zeroing was
performed.
Unscrew the power sensor from
the device under test and repeat
zeroing.
Warning: Input overloaded The power at the input of the
power sensor exceeds the
permitted power
(23 dBm = 200 mW).
Reduce the power at the sensor
input.
Power sensor hardware error Communication error between
the R&S FSH and the power
sensor.
Unscrew the sensor from the
R&S FSH and check the
connectors. If the problem
persists, contact a Rohde &
Schwarz service center.
Power sensor error The power sensor signals an
error to the R&S FSH.
Contact a Rohde & Schwarz
service center.
Unknown power sensor model
connected
The R&S FSH cannot identify the
device connected to its POWER
SENSOR connector.
