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)

C A U T I O N	Do not exceed +18 dBm source power. The Agilent 86120C’s input circuitry can
	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.

1Connect the laser’s output to the optical attenuator’s input.

2Connect the optical attenuator’s output to the optical power meter.

3Adjust the attenuator for a reading of 0 dBm on the power meter. Record the attenuator’s setting.

Attenuation at 0 dBm: ____________

4Adjust the attenuator for a reading of –35 dBm on the power meter. Record the attenuator’s setting.

Attenuation at –35 dBm: ____________

5Disconnect the fiber- optic cable at the power meter’s input and connect the cable to the Agilent 86120C being tested.

6Reset the optical attenuator to the setting recorded in Step 3.

7Read the power and wavelength measured on the Agilent 86120C, and compare them to the specifications listed in Chapter 6, “Specifications and Regulatory Information”.

8Reset the optical attenuator to the setting recorded in Step 4.

9Read the power and wavelength measured on the Agilent 86120C, and compare them to the specifications listed in Chapter 6, “Specifications and Regulatory Information”.
