Test 2. Sensitivity

Test 2. Sensitivity
Sensitivity is verified using the following devices:
Do not exceed +18 dBm source power. The Agilent 86120B's input circuitry can
be damaged when total input power exceeds 18 dBm.
Perform the following procedure first using the 1310 nm laser and then repeat
the steps using the 1550 nm laser.
