SOURce:SWEep Subsystem
This subsystem contains the commands to control the RF sweep, i.e., sweeps of the RF generators.
Sweeps are triggered on principle. The frequency sweep is activated by command
SOUR:FREQ:MODE
SWE
, the level sweep by command
SOUR:POW:MODE SWE
.

[:SOURce]:SWEep[:FREQuency]
The commands to set the frequency sweeps are under this node. Keyword [
:FREQuency
] can be
omitted (cf. examples). The commands are SCPI compatible then unless stated otherwise.
[:SOURce]:SWEep[:FREQuency]:DWELl 10 ms to 5 s
The command sets the dwell time per frequency step.
Example:
:SOUR:SWE:DWEL 12ms
*RST value is 15 ms
[:SOURce]:SWEep[:FREQuency]:MODE AUTO | MANual | STEP
The command specifies the run of the sweep.
AUTO Each trigger triggers exactly one entire sweep cycle.
MANual Each frequency step of the sweep is triggered by means of manual control or a
SOUR:FREQ:MAN
command, the trigger system is not active. The frequency
increases or decreases (depending on the direction of the shaft encoder) by the
value indicated under
[:SOUR]:FREQ:STEP:INCR
.
STEP Each trigger triggers only one sweep step (single-step mode). The frequency
increases by the value indicated under
[:SOUR]:SWE:STEP:LOG
.
Example:
:SOUR:SWE:MODE AUTO
*RST value is AUTO
