Appendix B: Automatic Measurements Reference
This reference describes the automatic measurement system of this instrument.
Automatic measurements support Pulse, Return-to-Zero (RZ), and Non-Return-
to-Zero (NRZ) signals, providing measurements in three categories, Amplitude,
Timing, and Area.
This reference gathers reference information for automatic measurements.
Specifically, it lists:
H
A definition for each auto-measurement type (for example, risetime, period,
and suppression ratio), organized according to the signal measured (Pulse,
Return-to-Zero eye pattern, or Non-Return-to-Zero eye pattern):
H
Pulse signals -- see Pulse Measurements on page B--2.
H
Return-to-Zero eye patterns -- see RZ Measurements on page B--15.
H
Non-Return-to-Zero eye patterns -- see RZ Measurements on page B--37.
H
Descriptions of the reference parameters (levels and crossings) that the
automatic measurement system uses when taking automatic measurements.
See
Measurement Reference Parameters and Methods on page B--56.
H
Descriptions of the methods for tracking the High and Low values that the
automatic measurement system uses when in taking automatic measure-
ments. See
High/Low Tracking Method on page 3--77.
To learn about the controls that set up the automatic measurements, see the
Tracking Methods section on page B--66 or Measurement Setup dialog box topic
