Chapter 5 Measurement Functions
5-68
This function has following setting items.
● ISS Method
This selects measurement method.
IEC:
This measurement method conforms to IEC standards.
Advanced:
This measurement method has less error due to optical input ASE
noise than IEC or Off.
Off:
This measurement method is equivalent to “5.7.1 Optical Amplifier
Measurement Method”, Spect Div Off.
● Channel Parameter
This sets the optical signal level range and the wavelength detection
method.
For details, see 5.8.2 “How to Set the Signal Measurement Method”.
● Opt Amp Test Parameter
This sets the Opt Amp Multi measurement’s ASE display, detection
method, NF calculation method, and the actual resolution calculation
method.
For details, see 5.8.3 “How to Set the Estimated Noise Measurement
Method”.
● Write to
This selects the signal to be measured.
Pin:
This measures the optical input.
Pout:
This measures the optical output.
● Display Mode
This selects the measurement results display method.
For details, see 5.8.1 “Optical Amplifier (WDM) Screen Display”.
● 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.
