SOURce<Ch>:POWer<PhyPt>:STATe
<Boolean>
Turns the RF source power at a specified test port on or off.
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer
Parameters:
<Boolean>
ON | OFF - turns the internal source power at the specified test
port no.
<PhyPt>
on or off.
*RST:
ON
Example:
*RST; SOUR:POW -6
Set the internal source power for channel 1 and all test ports to -6
dBm.
SOUR:POW2:STAT?
Query whether the source power at test port 2 is on. The analyzer
returns a
1
.
SOURce<Ch>:POWer<PhyPt>:STARt
<StartPower>
SOURce<Ch>:POWer<PhyPt>:STOP
<StopPower>
These commands define the start and stop powers for a power sweep. The values also
define the left and right edges of a Cartesian diagram. A power sweep must be active (
POWer
) to use these commands.
Suffix:
<Ch>
.
Channel number
<PhyPt>
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.
Parameters:
<StopPower>
Start or stop power of the sweep.
Range:
-150 dBm to +100 dBm. The usable power range is
frequency-dependent; refer to the data sheet.
Increment: 0.01 dB
*RST:
-25 dBm start power, 0 dBm stop power
Default unit: dBm
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.
Manual operation:
See
"Start / Stop / Center / Span Frequency (Power / Time)"
Note:
If the start power entered is greater than the current stop power
(
SOURce<Ch>:POWer<PhyPt>:STOP
), the stop power is set to the start power plus the
minimum power span (increment) of 0.01 dB.
