Status Reporting Commands

*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 .
