CONDITION:

Good cosmetic condition. LCD display is very clear. Variable attenuator is verified working at our lab.

At 1550nm with SM fiber jumpers, we tested insertion loss (including one-connector loss) with HP81525A optical head:
Set -0.5dB, IL=2.673dB. (This is minimum loss)
Set 0dB, IL=3.190dB.
Set 10dB, IL=13.621dB.
Set 20dB, IL=24.238dB.
Set 30dB, IL=34.374dB.
Set 40dB, IL=44.400dB.
Set 50dB, IL=53.55dB (accuracy is limited by optical head).
