Measuring Waveforms
3- 80
CSA8000B & TDS8000B User Manual
The AOP method is the Average Optical Power reference level. This reference
level selection is best used when taking the Optical Modulation Amplitude
(OMA) measurement on a pulse waveform. (The AOP setting is ignored for
NRZ waveforms.) This method is selected by default when measurement type is
set to OMA. See the OMA measurement on page B--5.
Default Methods.
The waveform-characterization methods just covered—the
High/Low-tracking and the reference-level-calculation methods used—can be set
for each measurement and its waveform source in the Meas Setup dialog box. If
you do not set the methods individually, the instrument uses its default character-
ization methods.
Use the procedure that follows to quickly take a measurement based on the
default settings for High/Low method and for reference-level method.
