The power sensor has a memory containing frequency-dependent correction values. This means that
the highest accuracy is reached for signals whose frequency is known. If the R&S FSH3 switches over
to the power measurement mode from another operating mode, it uses the center frequency as the
frequency for the power sensor.
If you want to perform measurements on another known signal, the power sensor can be “told” what the
center frequency is via the frequency entry mode (FREQ softkey).
¾ Press the FREQ softkey.
The frequency value entry box opens.
¾ Using the number keys, enter the frequency you
want and confirm the entry with the ENTER key or
by pressing the FREQ softkey again.
The R&S FSH3 transfers the new frequency to the
power sensor which then corrects the measured power
readings.
