Example:
Assume that a DUT requires a constant input power of +35 dBm
at port 2, and that the measurement path contains an amplifier
with a 30 dB gain.
*RST; SOUR:POW 0
Reset the instrument and set the internal source power (base
channel power) for the default channel 1 to 0 dBm.
SOUR:POW2:OFFS 5, ONLY
Replace the source power at port 2 by +5 dBm. The powers at
the remaining ports are not affected.
SOUR:POW2:CORR:LEV:OFFS 30
Specify the gain of the amplifier in the signal path between the
analyzer port 2 and the input port of the DUT.
SOUR:POW:CORR:ACQ PORT,2
Perform a source power calibration using port 2 as a source port
and the target power of +35 dBm.
Manual operation:
See
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
<IntSourcePow>
Defines the power of the internal signal source (channel base power). The setting is
valid for all sweep types, except power sweep.
Tip:
and
to define the sweep range for a power sweep.
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.
It is possible though to define a port-specific slope factor for the
source power (
SOURce<Ch>:POWer<PhyPt>[:LEVel][:
) and a port-specific power offset
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:
).
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.
