The Common Commands

Definition	The instrument setting is stored in RAM. You
	can store settings in locations 1-9. The scope of
	the saved setting is identical with the scope of
	the standard setting described in “*RST” on
	page 99.
Example	OUTPUT 728;"*SAV 3"

*SRE

Syntax	*SRE <wsp> <value>
	0 ≤ value ≤ 255
Definition	The service request enable command sets bits
	in the service request enable register that
	enable the corresponding status byte register
	bits.
	The register is cleared:
	• At power-on
	• By sending a value of zero.
	The register is not changed by the *RST and
	*CLS commands.
