Calibration Overview

Remote Operation Optical Power Calibration

The following procedure is for calibration of the MPS−8033 optical power via GPIB. The 8033 utilizes
a 3−point calibration to characterize the power response of the internal laser diode. It may help to be
familiar with front panel calibration before attempting it remotely.

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.
Connect the Optical Power Meter to an appropriate AC Power Source. Turn on the power
and comply with any warm up considerations. 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.
Remotely configure the MPS−8033 by using the following GPIB commands:
*CLS
LAS:STEP 0.0001 MW
Remotely configure the power meter for the following. This example assumes the ILX
Lightwave OMM−6810B is being used.
*CLS
POWER: AUTO ON
RATE SLOW
WAVE xxxx
Where xxxx = wavelength of 8033 source in nanometers.
Start the calibration by sending the following command to the 8033.
CAL:START
Create a software loop using the increment and decrement commands to adjust the
output power from the 8033. Stay in the loop until the dislayed power of the 8033 is within
0.0001 mW of the measured power from the power meter. Use the following 8033
commands as necessary:
LAS:INC
LAS:DEC
Use the following OMM−6810B Power Meter command to read the actual power:
POW?
When the power measurements between the meter and the 8033 are within 0.0001 mW,
send the following command to the 8033:
CAL:USER1
