1 ... Test port number of the analyzer, 1 to 2, 3 or 4, depending on the
analyzer model.
*RST value 1 (test port 1)
SCPI, Command
Types Device-specific, with query.
Example:
CALC4:PAR:SDEF "Ch4Tr1", "A1"
Create channel 4 and a trace named Ch4Tr1 to measure the wave
quantity a1.
CALC4:PAR:SEL "Ch4Tr1"
Select Ch4Tr1 as the active trace
.
SENS4:SWE:SRCP 2
Select drive port 2 for the active trace.
[SENSe<Ch>:]SWEep:STEP <step_size>
Sets the distance between two consecutive sweep points.
This setting is valid for sweep types with equidistant sweep points only. It does not apply to
logarithmic and segmented sweeps.
<Ch> Channel number.
<step_size>
Stimulus step size.
Range [def.
unit]
Depending on the other channel settings. The minimum step size is
equal to the sweep span divided by the maximum number of points
minus one ([SENSe<Ch>:]SWEep:POINts), the maximum step size is
equal to the sweep span ([SENSe<Ch>:]FREQuency:SPAN). See also
description of manual control and program example below. [–]
*RST value Depending on the analyzer model. The default step size is equal to the
default sweep span of the analyzer divided by the default number of
points minus one.
SCPI,
Command
Types
Confirmed, with query.
Example:
*RST; SWE:STEP?
Query the default step size. For a 25 GHz analyzer, the response is
119950000. 119950000 Hz = (24 GHz – 10 MHz) / 200.
SWE:STEP UP
Increase the step size.
FREQ:STOP?; :SWE:POIN?
Query the stop frequency of the sweep and the number of points.
Increasing the step size has changed both values.
