Local Operation Optical Power Calibration; Calibrating From The Front Panel - ILX Lightwave MPS-8033 Series User Manual

Local Operation Optical Power Calibration

The following procedure is for manual calibration of the MPS−8033 optical output power. Remote
calibration is discussed in Remote Operation Optical Power Calibration on page 78. The instrument
utilizes a 3−point calibration to characterize the power response of the source's laser diode.

Connect the 8033 to an appropriate AC power source. Turn the power on and allow the
8033 to warm up for at least one hour. Enable the laser output by pressing the (OUTPUT)
ON switch.
Connect the Optical Power Meter to an appropriate AC Power Source. Turn on the power
and configure it for the following:
MODE: Watts (linear)
RANGE: Auto or mW
FILTER: Slow
WAVELENGTH: Equal to the wavelength of 8033 source
(i.e. 1310 nm).
Comply with the warm−up considerations for the power meter. "Zero" the power meter per
the Power Meter's instructions.
Connect the calibration fiber optic patch cord to the MPS−8033.
Connect the other end of the patch cord to the Optical Power Meter. Make sure the
connections are clean and tight.
Start the calibration by simultaneously pressing LOCAL/ADR and (MODE) CW. The
display clears for two seconds before the output is turned on and the power is set to the
first calibration value.
Using the ADJUST KNOB, change the power until the 8033 display exactly matches the
power displayed on the power meter.
Press SET REFERENCE to store the first calibration point into memory. The 8033 then
switches to the next calibration value.
