Mode for Optical Power Measurements

PM (PM1 or PM2)/TLTS: use the OPM test mode to measure any incoming optical signal level
(CW, 270, 330, 1000, or 2000 Hz) between the wavelength range of 800 - 1700 nm. Then select
a calibrated wavelength that matches the incoming source wavelength.
8.2 Optical Power Measurements
To use FX87 for optical power measurements, connect the fiber to the OPM port located on the
right on the top panel of the device.

8.2.1 Setting ZERO Level

Set the ZERO level before the first use of FX87 for broadband power
measurements. We also strongly advise to set the ZERO level before every new
batch of measurements, and after measurement conditions have changed.
To set the ZERO level:
1. Press the |MODE|
2. Press |F3| (MORE), then press
