Operating Manual 1145.1084.12 – 30 996
Use SOURce<Ch>:POWer<Pt>:STARt and SOURce<Ch>:POWer<Pt>:STOP to define the sweep
range for a power sweep.
<Ch>
Channel number.
<Pt>
Test port number of the analyzer. This suffix is ignored because the selected channel
power applies to all source ports used in the active channel. It is possible though to
define a port-specific power limit
(SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]LLIMit:VALue) and a slope
factor for the source power
(SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]:SLOPe). Moreover, it is
possible to define a port-specific power offset
(SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]:OFFSet).
<power>
Internal source power.
Range [def.
unit]
–40 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 0.1-dB
steps.
*RST value
–10 dBm

Types
Confirmed, command or query
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as measured parameter for
channel and trace no. 1.
SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
SOUR:POW2:SLOP 10
Set the power slope factor for the wave transmitted at port 2 to 10 dB/GHz. The internal
source power and the waves at the other test ports are not affected.
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]:LLIMit:DGRaccess <Boolean>
Optimizes the automatic level control (ALC) for test setups where the additional connectors of option R&S
ZVA<frequency>-B16 are used. If the optimization is enabled, the ALC is limited to +1 dB so that the
active port power limits cannot be exceeded by more than 1 dB.
This command is unavailable unless option R&S ZVA<frequency>-B16, Direct Generator and
Receiver Access, is installed.
<Ch>
Channel number. This suffix is ignored; the setting applies to all channels.
<Pt>
Test port number of the analyzer. This suffix is ignored; the setting applies to
all ports.
<Boolean>
ON | OFF: Optimize ALC for additional connectors | use normal ALC
algorithm
*RST value
The setting is not changed after a *RST. The factory setting is OFF.
