Measurements on CW Signals
R&S FSH
1145.5973.12 2.8
E-14
The R&S FSH opens the screen and the menu for the power measurement. If no power sensor is
connected, no measured value is displayed. If a power sensor is connected, the R&S FSH establishes
a connection to the power sensor via the interface and, after a few seconds, displays the connected
power sensor type (R&S FSH-Z14 or R&S FSH-Z44) as well as the measured forward power and return
loss of the load.
Before performing the power measurement, zero the power sensor.
Press the ZERO softkey.
The R&S FSH informs you not to apply any signals
while the power sensor is being zeroed.
Disconnect the power sensor from any signal
sources.
Start zeroing with the first or second softkey
(CONTINUE).
Softkey 4 or 5 (CANCEL) can be used to cancel
zeroing before it begins, e.g. if the signal source
cannot be disconnected.
The R&S FSH immediately starts power sensor zeroing. While this is being done, the R&S FSH outputs
the message "Zeroing power sensor, please wait...".
When zeroing is over, the R&S FSH outputs the message "Power Sensor Zero OK" and switches back
to the softkey menu for the power sensor.
Now connect the R&S FSH-Z14 or R&S FSH-Z44 between the source and the load.
The R&S FSH displays the measured forward power level in dBm and the VSWR of the load.
To achieve maximum measurement accuracy, enter the frequency of the signal under test.
Press the FREQ softkey.
The R&S FSH opens the entry box for the frequency.
Using the numeric keys, enter the desired frequency
and terminate the input with the ENTER key or by
pressing the FREQ softkey again.
The R&S FSH transfers the new frequency to the
power sensor which then corrects the measured power
readings.
