4.17 Source Subsystem - Frequency

This subsystem programs the output frequency of the AC source.

Subsystem Syntax

[SOURce:]

FREQuency

[:CW | :IMMediate]

Sets the frequency

:MODE

Sets frequency mode (FIX|STEP|PULS|LIST|SENS|EXT)

:SLEW

[:IMMediate] | INFinity

Sets the frequency slew rate

:MODE

Sets frequency slew mode (FIX|STEP|PULS|LIST)

:TRIGgered | INFinity

Sets the triggered frequency slew rate

:TRIGgered

Sets the triggered frequency

FREQuency

This command sets the frequency of the output waveform.

Command Syntax

[SOURce:]FREQuency[:CW|:IMMediate]

Parameters

45 to 5000

Unit

HZ (Hertz)

*RST Value

60 Hz

FREQ:MODE FREQ:SLEW

FREQuency:MODE

This command determines how the output frequency is controlled. Available modes are:

FIXed

The output frequency is unaffected by a triggered output transient. The
clock source is the internal controller timebase.

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.

SENSe

External sync or line sync clock mode. The frequency is synchronized to
the external sync or line sync frequency. See Lx/Ls user manuals for
sync operation details.

EXTernal

External clock mode. This mode is used on an Lx/Ls unit with the

–LKS

option to sync to a master Lx/Ls unit.
