SCPI Instrument Command List

Command	:ROSC:SOUR
Long	[:SOURce]:ROSCillator:SOURce
Form	Set & Query
Parameter	INTernal EXTernal
*RST value	INT
Description	Use this command to set/read the reference source for the PLL. If you
	select the external reference (CLK IN connector) you can choose to use a
	1 MHz, 2 MHz, 5 MHz or 10 MHz reference signal using
	:ROSC:EXT:FREQ.
	INTernal	Lock the PLL to its internal reference
	EXTernal	Lock the PLL to a reference signal at the CLK IN connector. The exter-
		nal reference signal can be 1, 2, 5 or 10 MHz.
Example	:ROSC:SOUR EXT		Set external PLL reference (CLK IN)
	:ROSC:EXT:FREQ 10 MHZ		Set expected PLL reference frequency
			to 10 MHz

Command	:ROSC:EXT:FREQ
Long	[:SOURce]:ROSCillator:EXTernal:FREQuency
Form	Set & Query
Parameter	Numeric
*RST value	5 MHz
Specified limits	1 MHz, 2 MHz , 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 1, 2, 5 or 10
	MHz signal. Note that if you program any value other than the specified
	values, the value will be set to the nearest of the specified values.
Example	:ROSC:SOUR EXT	Set external PLL reference (CLK IN)
	:ROSC:EXT:FREQ 10MHZ	Set expected PLL reference frequency to 10 MHz
