OPM
This function is used to test the power of optical signal and insertion loss of various
devices and optoelectronic components. It can identify and measure the
frequency of 270/330/1k/2kHz frequency optical signal.
F1: Switching wavelength
F2: Setting Reference Power F3:Zero Reference Power
F4: Enter the Calibration Mode
Absolute power,relative power and linear power are converted as follows:
