Command
*OPC?
Description
Operation Complete Query.
Explanation
Returns 0 if a long-term operation is ongoing.
Returns 1 if no long-term operation is ongoing.
The laser has three long-term operations:
Scanning
(see OUTPut:SCAN:STARt)
Resetting
(see OUTPut:SCAN:RESEt)
Wavelength Set (see [SOURce]:WAVElength)
Starting any of the above three operations clears the OPC status bit. When
the laser reaches the target wavelength, the OPC status bit is set to 1. The bit
is also set to 1 if the movement is interrupted, either with SCAN:STOP, which
interrupts a SCAN or RESEt, or OUTPut:TRACk OFF, which interrupts a
Wavelength Set.
Example
During a wavelength scan:
*OPC?
—> 0
and when the scan is completed:
*OPC?
—> 1
