R&S SMB Command Description
1407.0806.32 6.79 E-2
[SOURce:]SWEep[:FREQuency]:DWELl 3 ms...10 s
The command sets the time taken for each frequency step of the sweep.
Note:
It is recommended to switch off the GUI update for optimum sweep performance especially with
short dwell times (SYSTem:DISPlay:UPDate OFF).
The keyword [:FREQuency] can be omitted (see example). The command is then SCPI-compliant.
Example:
SWE:DWEL 12 ms 'sets a dwell time of 12 ms for a frequency sweep.
*RST value Resolution Options SCPI
10 ms 0.1 ms Device-specific
[SOURce:]SWEep[:FREQuency]:EXECute
The command triggers a sweep. The command is only valid for sweep mode Single
(SOURce:SWEep:FREQuency:MODE SINGle). The command corresponds to the manual-control
command EXECUTE SINGLE SWEEP.
The command triggers an event and therefore has no query form and no *RST value.
Example:
SWE:FREQ:MODE SING 'sets the single cycle mode of the frequency sweep.
SWE:FREQ:EXEC 'triggers a single frequency sweep.
*RST value Resolution Options SCPI

[SOURce:]SWEep[:FREQuency]:MODE AUTO | MANual | STEP
The command sets the sweep mode.
The keyword [:FREQuency] can be omitted (see example). The command is then SCPI-compliant.
Parameters: AUTO
Each trigger triggers exactly one complete sweep.
MANual
The trigger system is not active. Each frequency step of the sweep is triggered
individually, either by varying the Current Frequency value using the rotary
knob under manual control or by means of a FREQ:MAN command under
remote control. With manual control, the frequency increases or decreases
(depending on the direction of the rotary encoder) by the value specified under
SOUR:SWE:FREQ:STEP:LIN (linear spacing) or ...:STEP:LOG (logarithmic
spacing). With remote control, the frequency increases by the value specified
under SWEep:FREQ:STEP:LIN|LOG which each sent :FREQ:MAN
command, irrespective the value entered there.
STEP
Each external trigger triggers one sweep step only (Mode Extern Step). The
frequency increases by the value entered under SOUR:SWE:FREQ:STEP:LIN
(linear spacing) or ...:STEP:LOG (logarithmic spacing).
Example:
SWE:MODE AUTO 'selects auto mode for a frequency sweep.
*RST value Resolution Options SCPI
