Usage
*ESR?
Details
The instrument returns a decimal value that corresponds to the binary-weighted sum of all bits set in
the register.
Bit
Decimal
value
Constant When set, indicates the following has occurred:
0 1
status.standard.OPC
All pending selected instrument operations are
complete and the instrument is ready to accept new
commands. The bit is set in response to an *OPC
(on page 6) command or TSP opc() (on page 8-230)
function.
