Test 2. Sensitivity

Test 2. Sensitivity
Description Sensitivity is verified using the following devices:
• Optical power meter
• Optical attenuator
• 1310 nm and 1550 nm lasers (>0 dBm output power)
Do not exceed +18 dBm source power. The Agilent 86120C's input circuitry can
C A U T I O N
be damaged when total input power exceeds 18 dBm.
Procedure Perform the following procedure first using the 1310 nm laser and
then repeat the steps using the 1550 nm laser.
1 Connect the laser's output to the optical attenuator's input.
2 Connect the optical attenuator's output to the optical power meter.
3 Adjust the attenuator for a reading of 0 dBm on the power meter.
Record the attenuator's setting.
Attenuation at 0 dBm: ____________
4 Adjust the attenuator for a reading of –35 dBm on the power meter.
Record the attenuator's setting.
Attenuation at –35 dBm: ____________
5 Disconnect the fiber- optic cable at the power meter's input and connect
the cable to the Agilent 86120C being tested.
6 Reset the optical attenuator to the setting recorded in
