SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
<IntSourcePow>
Defines the power of the internal signal source (channel base power).
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer. This suffix is ignored because
the selected channel base power applies to all source ports
used in the active channel.
Parameters:
<IntSourcePow>
Internal source power
Range:
The usable power range is frequency-dependent;
refer to the data sheet.
*RST:
-10 dBm
Default unit: dBm
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as mea-
sured parameter for channel and trace no. 1.
SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
Manual operation:
SOURce<Ch>:POWer<PhyPt>:SWEepend:MODE
<SweepEndModes>
Selects the power mode at sweep end.
This is a global setting.
Suffix:
<Ch>
.
Channel number. This suffix is ignored; the setting is valid for all
channels.
<PhyPt>
Physical port number. This suffix is ignored; the setting is valid
for all ports.
Parameters:
<SweepEndModes> AUTO | REDuce | KEEP
AUTO: at sweep end restore the power at sweep start
REDuce: at sweep end reduce the output power as if the chan-
nel base power was set to its minimum possible value
KEEP: at sweep end keep the power at its current level
Example:
SOURce:POWer:SWEepend:MODE REDuce
Reduce power at sweep end.
SOURce:POWer:SWEepend:SDELay 0.01
Use a settling delay of 10 ms
SOURce:POWer:SWEepend:MODE AUTO
At sweep end, restore the power at sweep start
