Frequency (Page 2)
The received signal frequency and offset is measured and displayed
For OTN signals, the measurement is performed on the optical interfaces (SFP for OTU-1) or (XFP for OTU-2).
OTN Current:
Indicates the frequency of the input signal
Offset (ppm):
Indicates the difference between the standard rate and the bit rate of the input signal
Min (ppm):
Indicates the difference between the standard rate and the minimum deviation detected in the input signal
Max (ppm):
Indicates the difference between the standard rate and the maximum deviation detected in the input signal
