*SRE <enable value>
This command enables bits in the Status Byte enable register.
*SRE?
Query 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?
Query the Status Byte summary register. The *STB? command is similar to a
serial poll but it is processed like any other instrument commands.
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
Instruct 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.
