IAMPlitude | IPHase
Amplitude | Phase imbalance sweep
Only available in source coherence mode (
SOURce<Ch>:
CMODe[:STATe] ON
).
The sweep properties can be set using SOURce:CMODe... com-
mands.
*RST:
LINear
Example: *RST
Reset the analyzer, activating a linear frequency sweep.
SWE:TYPE LOG
Change to a logarithmic frequency sweep, resetting the stimulus
values of the sweep points.
Manual operation: See "Lin Freq" on page 492
[SENSe<Chn>:]SWEep:SRCPort <Port>
Sets/gets the source port for the stimulus signal. The setting acts on the active trace.
The effect of the drive port selection depends on the measurement parameter associ-
ated to the active trace:
●
If an S-parameter S
<out><in>
is measured, the second port number index
<in>
(input
port of the DUT = drive port of the analyzer) is set equal to the selected drive port:
Drive port selection affects the measured quantity.
●
If a wave quantity or a ratio is measured, the drive port is independent of the mea-
sured quantity:
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Port> Logical port number
*RST:
1
Example: CALC4:PAR:SDEF "Ch4Tr1", "A1"
Create channel 4 and a trace named "Ch4Tr1" to measure the
wave quantity a
1
. The trace automatically becomes the active
trace.
SENS4:SWE:SRCP 2
Select drive port 2 for the active trace.
CALC4:PAR:MEAS? "Ch4Tr1"
Query the measurement result for "Ch4Tr1". The response is
'A1D2SAM'
.
