Performance Verification Tests
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.
2. Configure the following settings:
a. Recall Default setup
b. Enable the channel with the OE695G, disable others
c. Configure the active channel for the optical wavelength
matching the laser source
d. Create a measurement for the mean value of the channel
e. 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 6). Press Clear Sweeps on the oscilloscope front panel. From the
