Operating Manual 1145.1084.12 – 30 1001
<Ch>
Channel number.
<Pt>
Test port number of the analyzer. This suffix is ignored because the selected
power sweep range applies to all source ports used in the active channel.
<numeric_value>
Stop power of the sweep.
Range [def. unit]
–39.99 dBm to +10 dBm. The exact range depends on the analyzer model;
refer to the data sheet [dBm]. UP and DOWN increment/decrement the source
power in 1-dB steps.
*RST value
0 dBm
SCPI, Command
Types
Confirmed, command or query
Example:
SWE:TYPE POW
Activate a power sweep.
SOUR:POW:STAR -6; STOP 10
Select a power sweep range between –6 dBm and +10 dBm.
If the stop power entered is smaller than the current start power (SOURce<Ch>:POWer<Pt>:STARt),
the start power is set to the stop power minus the minimum power span of 0.01 dB.

This subsystem controls the port and channel specific Automatic Level Control (ALC) settings.
SOURce<Ch>:POWer<Pt>:ALC:AUBW <Boolean>
