Options and accessories
Alternatively, the application program may continuously poll the
Operation Complete bit using *ESR?
*OPC?
This command sets the instrument's Operation Complete Query
State active. When any in-progress command is complete, the state
returns to idle, a '1' is placed in the output queue and therefore the
Message Available bit (4) is set.. The command should only be used
in conjunction with non-query commands and is only available for
IEEE.
Example
Data logging can take an appreciable time to execute, so it is useful
to program the instrument to generate a service request on
completion of the logging function.
The following command sequence can be used:
*SRE 16 Enables Message Available bit to trigger a service
request.
*CLS Clears the Message Available bit.
INITiate Initiates data logging. *OPC Sets
RQS on completion of the log
Alternatively, the application programme may continuously poll the
Message Available bit using *STB?
*RST
Clears all pending operations, resets the Operation Complete
Command State and Operation Complete Query State.
*SRE <NRf>
Enable bits in the Service Request Enable Register. The selected
bits are then reported to the Status Byte.
*SRE?
Query the Service Request Enable Register. The instrument returns
a decimal value that corresponds to the binary-weight sum of all bits
set in the register.
