Programming Reference

SCPI Instrument Command List

Example To set and activate the current limits for the output:

Command :FREQ

Long [:SOURce]:FREQuency[:CW|:FIXed]

Form Set & Query

Parameter Numeric

Parameter Suffix Hz with engineering prefixes, or MHZ for Megahertz.

Value coupling

*RST value 1.00 MHz

Specified limits 1mHz to 50MHz

Description Use this command to set/read the pulse frequency. Select the frequency

source for the pulse frequency using :TRIGger:SOURce. The currently

selected source is programmed by this command. Note that the sp ecified

limits and available resolution depend on the selected source.

You cannot set the pulse frequency if you have selected the CLK-IN

connector as the frequency source (:TRIG:SOU R EXT).

Example To set the pulse frequency to 40MHz:

:HOLD CURR

:CURR:LIM 50MA

:CURR:LIM:LOW –50MA

:CURR:LIM:STAT ON

Enable CURRENT subsystem

Set OUTPUT high level current limit to 50 m

Set OUTPUT low level current limit to –50m

Switch on OUTPUT limits

Period = 1Frequency

:TRIG:SOUR INT

:FREQ 40MHz

Select internal osc. as pulse trigger

Set pulse frequency to 40 MHz
