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]
Sets the frequency slew rate
:MODE
Sets frequency slew mode (FIX|STEP|PULS|LIST)
:TRIGgered
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.
