Status Reporting Commands

4
*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
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.
