1325User Manual 1173.9163.02 ─ 62
Parameters:
<SweepPoint> Number of points per sweep
Range: see above
*RST: 201
Example:
*RST
Reset the instrument, activating a frequency sweep with 201
sweep points.
SWE:TIME?
Query total sweep time.
SWE:POIN 2010
Multiply the (default) number of points by 10.
SWE:TIME?
Query total sweep time again. The analyzer estimates a sweep
time that is also multiplied by 10.
Manual operation: See "Number of Points" on page 415
[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'.
[SENSe<Ch>:]SWEep:STEP <StepSize>
Sets the distance between two consecutive sweep points in a (non-segmented) linear
frequency sweep.
