SCPI Instrument Command List

Example To set up the external PLL reference:

Command :ROSC:EXT:FREQ

Long [:SOURce]:ROSCillator:EXTernal:FREQuency

Form Set & Query

Parameter Numeric

*RST value 5 MHz

Specified limits 5 MHz or 10 MHz

Description Use this command to set/read the expected reference frequency for the

PLL at the CLK-IN connector. The external reference can be a 5 or

10 MHz signal. Note that if you program any value other than the two

specified values, the value will be set to the nearest of the two specified

values.

Example To set up the external PLL reference:

:ROSC:SOUR EXT

:ROSC:EXT:FREQ 10 MHZ

Set external PLL reference (CLK-IN)

Set expected PLL reference frequency to

10 MHz

:ROSC:SOUR EXT

:ROSC:EXT:FREQ 10MHZ

Set external PLL reference (CLK-IN)

Set expected PLL reference frequency to

10 MHz
