Handling Precautions
Whenever handling the photoreceiver, make sure to
follow these precautions:
• Follow standard electrostatic-discharge
precautions, including grounding yourself prior to
handling the detector or making connections—
even small electrostatic discharges could
permanently damage the detector. A ground strap
provides the most effective grounding and
minimizes the likelihood of electrostatic damage.
• Do not over torque the microwave K-connector.
Excessive torque can damage connectors.
• Make sure the optical connector is clean and
undamaged before connecting it to the detector
module.
Connecting the Power Supply and Bias
1.
Prior to handling the detector, ground yourself
with a grounding strap to prevent electrostatic
damage to the receiver.
2.
Connect the power cable to the power supply. Two
power cables were included with the receiver; use
the appropriate cable for your power supply.
Connecting to a New Focus power supply:
Use
the cable with the two round microconnectors.
Connect one end of the cable to one of the power
supply’s 300-mA outputs.
Connecting to another power supply:
Use the
cable with the round microconnector on one end
and three banana plugs on the other end. Be
careful to connect the banana plugs to the power
supply as follows; connect the red plug to a well-
regulated, +15-V, 200-mA source; connect the
black plug to a -15-V, 200-mA source; connect
