Operation Complete Definition
Note that Bit 0 of the Standard Event Status Register contains the status of the
Operation Complete flag. Enabling this bit via the *ESE command allows the user
to update Bit 5 of the Status Byte. Then, if the SRE mask has Bit 5 set, and the
user issues an *OPC command, the SRQ signal will be generated upon
completion of the currently processed commands. This may be used to initiate
service request routines which depend on the completion of all previous
commands.
Operation Complete on the LDX-36000 is defined as:
• No operations to the laser current source hardware are pending.
• No EEPROM (non-volatile) memory write cycles are in progress.
Note: If the GPIB times out while waiting for a response, either set the GPIB time-out
longer or use SRQ-generated interrupts. See the GPIB interface manual for time-out
configuration or SRQ programming setup. The *OPC, *OPC?, and *WAI commands
should not be used inside a calibration routine.
