10 Using the same methodology in step 8, create a loop to achieve the second power
calibration value.
11 When the power measurements between the meter and the 8033 are within 0.0001 mW,
send the following command to the 8033:
CAL:USER2
12 Using the same methodology in step 8, create a loop to achieve the final power calibration
value.
13 When the power measurements between the meter and the 8033 are within 0.0001 mW,
send the following command to the 8033:
CAL:USER3
14 The calibration is complete. The new calibration factors will be stored into non−volatile
RAM for safe keeping when the power to the device is turned off.
Recalling the Factory Calibration
To reset the 8033 to the default calibration, send the following command via GPIB.
CAL:RECALL
When this command is issued the present calibration values are lost and the default calibration is
reset. ILX Lightwave recommends a user calibration after you execute this command.
Cleaning the Internal Fiber Optic Connector
Occasionally the fiber optic output connector on the 8033 becomes dirty. This section describes two
procedures for cleaning the end of the output fiber. The first method is the easiest way to clean the
fiber end, while the second if extremely dirty connectors.
First method:
1 Dampen a small cotton swab with some reagent grade methanol.
2 Insert the swab into the FC bulkhead connector until it touches the end of the internal
fiber.
3 Remove the swab. Do not rotate the cotton swab when it is in contact with the fiber
end , as scratching of the fiber end may occur due to small pieces of dirt sitting there.
This cleaning procedure may be used as many times as necessary to remove
contamination from the fiber end.
