SCPI Instrument Command List

Command :FREQ:AUTO

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

Form Event

Parameter ONCE

*RST value Not applicable

Description Use this command to measure the frequency at the CLK-IN connector. If

the CLK-IN connector is the selected pulse f requency source, you can

then read the measured value with :FREQ?

Example To measure and read the frequency at the CLK-IN connector:

Command :HOLD

Long [:SOURce]:HOLD

Form Set & Query

Parameter VOLTage | CURRent

*RST value VOLT

Description Use this command to enable either of the [:SOURce]:VOLTage or

[:SOURce]:CURRent subsystems.

You can control the signal levels of the instrument’s OUTPUT in terms of

voltage or current.

:TRIG:SOUR EXT

:FREQ:AUTO ONCE

:FREQ?

Select ext CLK-IN as pulse trigger
