Status Reporting Commands
120 E3632A User’s Guide
*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.
