Status Reporting Commands

*PSC?

This command queries the power-on status clear setting. The returned parameter is ‘‘0’’ (*PSC 0) or ‘‘1’’ (*PSC 1).

*SRE <enable value>

This command enables bits in the Status Byte enable register.

*SRE?

This command queries the Status Byte Enable register. The power supply returns a decimal value which corresponds to the binary-weighted sum of all bits set in the enable register.

*STB?

This command queries the Status Byte summary register. The *STB? command is similar to a serial poll but it is processed like any other instrument command. The *STB? command returns the same result as a serial poll but the ‘‘Request Service’’ bit (bit 6) is not cleared if a serial poll has occurred.

*WAI

This command instructs the power supply to wait for all pending operations to complete before executing any additional commands over the interface. Used only in the triggered mode.
