Measuring the channel power of continuously modulated signals R&S FSH
1309.6275.12 4.38 E-2
Operation:
Press the SPAN key.
The AUTO SPAN softkey label is highlighted in green
to indicate that the optimum span for the channel
power measurement is set. MANUAL SPAN is
activated to allow immediate entry of another span.
Using the numeric keys, enter a new span and
terminate the entry with the appropriate unit, or
Change the span with the rotary knob or the cursor
keys and terminate the entry with the ENTER key
or the MANUAL SPAN softkey.
The largest permissible span for the channel power measurement is ten times the channel bandwidth.
At larger spans, the result of the channel power measurement would be increasingly imprecise,
because too few points of the trace occur in the channel to be measured.
Press the AUTO SPAN softkey to again set the optimum span.
To return to the menu for channel power measurement, press the MEAS key.
Measurement of maximum channel power:
If signal levels fluctuate significantly, you can define the maximum channel power by using the Max
Hold function.
Operation:
Press the POWER DISPLAY softkey.
Select MAX HOLD by using the cursor keys or the
rotary knob and then confirm with the POWER
DISPLAY softkey or the ENTER key. The power
display will switch from "Power" to "Max Power".
To deactivate the Max Hold function, press the
POWER DISPLAY softkey.
Select CLEAR/WRITE by using the cursor keys or
the rotary knob and confirm with the ENTER key.
The power display will switch from "Max Power" to
"Power".
