Generates a single sweep cycle after a trigger event.
The sweep steps within the cycle are performed automatically, con-
trolled by the dwell time. If one cycle is completed, the instrument
waits for the next trigger event.
To trigger the sweep, use "Execute Single Sweep" button, or the cor-
responding remote control commands, for example *TRG.
Example:
SOUR:LFO:SWE:FREQ:MODE AUTO
TRIG0:SWE:SOUR SING
SOUR:LFO:FREQ:MODE SWE
SOUR:LFO:SWE:FREQ:EXEC
Generates the sweep signal step-by-step, manually triggered.
To perform the sweep steps, enter the frequency value under
Freq.
Example:
SOUR:LFO:SWE:FREQ:MODE MAN
SOUR:LFO:FREQ:MODE SWE
SOUR:LFO:SWE:FREQ:SPAC LIN
SOUR:LFO:SWE:FREQ:STEP:LIN 1E34
SOUR:LFO:FREQ:MAN 12 kHz
The value entered with command
SOUR:LFO:SWE:FREQ:STEP:LIN|LOG sets the step width.
The value entered with command SOUR:LFO:FREQ:MAN has no
effect, the command only sets the next sweep step. In remote control
only a step-by-step sweep from start to stop frequency is possible.
Generates a single sweep cycle when an a external trigger event
occurs.
The sweep steps within the cycle are performed automatically, con-
trolled by the dwell time. If one cycle is completed, the instrument
waits for the next trigger event.
To trigger the sweep, apply an external trigger signal.
Refer to the description of the rear panel for information on the con-
nectors for external trigger signal input (see
Tour", on page 21).
Example:
SOUR:LFO:SWE:FREQ:MODE AUTO
TRIG0:SWE:SOUR EXT
SOUR:LFO:FREQ:MODE SWE (External trigger)
