Handling Precautions
Whenever handling the photoreceiver, make sure to
follow these precautions:
•
Prior to handling the unit or making connections,
be sure to ground yourself adequately—even small
electrostatic discharges could permanently dam-
age the device. A ground strap provides the most
effective grounding and minimizes the likelihood
of electrostatic damage.
•
Make sure the optical connector is clean and
undamaged before connecting it to the detector
module.
Using the Photodetector
To obtain optical input:
1.
Plug one end of the power cable to the connec-
tor on the back of the module and the other end
into a ±15-V power supply. (We recommend the
New Focus Model 0901 power supply.) Turn on
the supply.
Two different power cables have been shipped
with your detector: a Model 0921 banana plug-to-
microconnector cable and a Model 0922
microconnector-to-microconnector cable. If you
have a New Focus Model 0901 power supply, use
the Model 0922 cable on one of the supply’s 0.3-A
microconnector outputs. Do not use the Model
0921 on the Model 0901 power supply’s 0.1-A
banana outputs since they do not provide enough
current for the receiver. Use the Model 0921 cable
only with a power supply other than the 0901
