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.
