25 SYST:SCREENSAVER x Sets time setting for the screen saver (x is in minutes)
26 SYST:GPIBADDRESS? 9 Returns matrix system’s GPIB address
27 SYST:GPIBADDRESS x Sets matrix system’s GPIB address to x
31 *CLS Clear Status Command used to clear the Event Register in all register groups.
32 *ESE Command used to enable bits in the Standard Event Status Enable register.
33 *ESE? Query used to read the content of the Standard Event Status Enable register.
34 *ESR? Query used to read the content of the Event Status Register.
35 *OPC
Sets the Operation Complete bit in the Event Status Register when all pending operations have
been finished.
36 *STB? Query used to read the content of the Status Byte Register.
37 *SRE Command used to enable bits in the Service Request Enable register.
38 *SRE? Query used to read the content of the Service Request Enable register.
39 *WAI
This command prevents the matrix from executing any further commands or queries until the current
commands have been processed.
Note 1: Missing command numbers are commands reserved for Ethernet matrices and not applicable to GPIB models.
Note 2: Commands related to the GPIB controller’s registers *ESE, *ESE?, *ESR?, *STB?, *SRE, *SRE? can NOT
