Optical measurements
This dialog provides settings for testing optical signals. Optical measurements require
an optical power signal provided by an optical probe.
For accurate measurements, a dark calibration of the optical probe is required.

Meas. type
Description/Result
Average power
Measure for the true average component of an optical signal.
Optical modulation
amplitude (OMA)
Measure of the difference between the optical power of a non-return-to-
zero (NRZ) one pulse and the optical power of an NRZ zero pulse.
OMA requires an NRZ pattern.
The one pulse and zero pulse levels are measured in the level mea-
surement window defined with
and
.
OMA is based on norm IEC 61280-2-2.
