Performance Verification
CW Gain
Required Equipment
•
OE695G and compatible oscilloscope
•
CW laser source at the desired optical wavelength
•
Variable optical attenuator (or use variable output level of CW source)
•
Optical power meter calibrated for the optical wavelength of the source
•
Multimode optical fiber patch cable
Procedure
1.
Connect the OE695G to a compatible oscilloscope channel and allow to
fully warm-up for at least 20 minutes.
2.
Configure the following settings on the oscilloscope:
•
Recall Default setup
•
Enable the channel with the OE695G, disable others
•
Configure the active channel for the optical wavelength matching the
laser source
•
Create a measurement for the mean value of the channel
•
Enable measurement statistics.
3.
Connect the optical attenuator (if used) input fiber to the laser source or
connect a fiber patch cable to the output of the laser source. Before
mating, carefully clean the fiber connections with an appropriate fiber
cleaning cloth.
4.
Set the attenuator/laser for an output level of approximately 60 uW.
5.
Connect the patch/attenuator output cable to the optical power meter
and note the Input Power Measurement: _________ uW
6.
With the OE695G optical input cover closed, perform a dark calibration
(page 5). Press Clear Sweeps on the oscilloscope front panel. From the
statistical mean value of the mean measurement, note the Residual Dark
Level:___________ uW
7.
Connect the patch/attenuator output cable to the OE695G optical input.
Press Clear Sweeps on the oscilloscope front panel, and using the
statistical mean of the mean measurement, note the Observed Power
Level:_____________ uW
