Figure 6-72: Power control at sweep end in Single Sweep mode (power sweep)
Note:
By default, at sweep end the output power of the first measurement point is
restored ("Auto" mode). After a small settling time (~10 ms), the sweep can be restar-
ted.
Selecting a different behavior can result in a significantly longer total measurement
time, in particular if a long "Settling Delay" is used. Do not forget to revert the
to "Auto" mode if it is not necessary to "Reduce" or "Keep" the
power at the sweep end. A preset is not sufficient for this purpose.
Power Mode at Sweep End ← Power Reduction at Sweep End
The analyzer offers three power modes at sweep end:
●
"Auto" results in the shortest measurement time (default setting). If enabled, at
sweep end the output power of the first measurement point is restored. The config-
ured
is not applied.
●
"Reduce" is intended for measurements on sensitive DUTs (primarily: power
sweeps). If enabled, at sweep end the output power of the driving port is reduced
as if the channel base power was set to its minimum possible value. The config-
ured settling delay is applied.
●
"Keep" is intended for power sweeps. If enabled, at sweep end the output power of
the last measurement point is kept. The configured settling delay is applied.
See
Note:
●
Compared to "Auto" mode, "Reduce" and "Keep" can result in significantly longer
measurement times - in particular if an extended settling delay is used.
●
The output power is not altered if there is only a single channel with a single driving
port, performing a "Time" or "CW Mode" sweep.
●
In triggered mode, the analyzer always uses the settings of the first measurement
point while waiting for the trigger signal.
