Source Subsystem (Frequency)
This subsystem programs the output frequency of the ac source.
Subsystem Syntax
[SOURce:]
FREQuency
[:CW | :IMMediate] <n> Sets the frequency
:MODE <mode> Sets frequency mode (FIX | STEP | PULS | LIST)
:SLEW
[:IMMediate] <n> | INFinity Sets the frequency slew rate
:MODE <mode> Sets frequency slew mode (FIX | STEP | PULS | LIST)
:TRIGgered <n> | INFinity Sets the triggered frequency slew rate
:TRIGgered <n> Sets the triggered frequency
FREQuency
This command sets the frequency of the output waveform.

FREQ:MODE FREQ:SLEW
FREQuency:MODE
This command determines how the output frequency is controlled during a triggered output transient. The
choices are:
FIXed
The output frequency is unaffected by a triggered output transient.
STEP
The output frequency is programmed to the value set by FREQuency:TRIGgered when a
triggered transient occurs.
PULSe
The output frequency is changed to the value set by FREQuency:TRIGgered for a duration
determined by the pulse commands.
LIST
The output frequency is controlled by the frequency list when a triggered transient occurs.
