Operation Complete Query
Syntax
*OPC?
Description
The laser has four long-term operations:
•
Turning on the system (system initialization)
•
Turning on the diode (:OUTPut ON)
•
Scanning (:OUTPut:SCAN:START)
•
Set Wavelength ([:SOURce]:WAVElength)
Starting any of these operations clears the OPC sta-
tus bit. When the laser returns to the start wave-
length or 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
OUTPutSCAN:ABORt, which interrupts a scan, or
OUTPut:TRACk OFF, which interrupts a wave-
length set.
Argument/Response
Returns 0 if a long-term operation is ongoing.
Returns 1 if no long-term operation is ongoing.
