Return-to-Zero (RZ) Measurements - Area
Table B--6 describes each RZ measurement in the area category. See Table B--4
on page B--15 for amplitude category measurements; see Table on B--5 on page
B--29 for timing category measurements
Table B- 6: RZ Measurements - Area
Name
Definition
RZ Area
The area under the curve for the RZ waveform within the measurement region. Area measured
above ground is positive; area measured below ground is negative.
over the measurement region.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2). See
To Localize a Measurement
on page 3--83.
This measurement requires the use of a waveform database. When this measurement is turned
on, it will automatically set the measurement system to use a waveform database if available.
See
Use a Waveform Database
on page B--70.
For best results with this measurement:
H
Perform a Dark Level compensation before taking this measurement if the source of the
measured waveform is an optical channel. See
To Perform Dark-Level and User
Wavelength Gain Compensations
on page 3--98.
H
Optimize the vertical resolution before taking this measurement. See

RZ Cycle Area
The area under the curve for the first RZ bit period. Area measured above ground is positive;
area measured below ground is negative.
Where the measurement region is from Start Gate (G1) to Stop Gate (G2), if measurement
gates are enabled, or the first acquired RZ cycle.
If enabled, measurement gates constrain the measurement region to the area between the Start
