● Ext. Trigger Delay
This sets the delay time for external sync measurement at pulse or
multiple division wavelength measurements. This function button is
not displayed in the measurements other than pulse or multiple
division wavelength measurements.
● Write to
This selects the signal to be measured.
Pin:
This measures the optical input.
Pout:
This measures the optical output.
Pase:
This measures the amplified spontaneous emission. It can be selected
at the polarization nulling method.
● Pin
This selects the traces A to J to store the input waveform.
● Pout
This selects the traces A to J to store the output waveform.
● Pase
This selects the traces A to J to store the ASE waveform.
See 5.7.7 “Calculation Method” for the formulas for each measurement
method.
