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.

is similar to a serial poll but it is processed like any other instrument command.

Service’’ bit (bit 6) is not cleared if a serial poll has occu rred.

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.
