Measurement Parameter Analysis
Overview
Teledyne LeCroy provides a variety of unique capabilities for advanced
measurement parameter analysis. Most Teledyne LeCroy oscilloscopes
calculate measurements for all instances in the acquisition. This provides
the ability to rapidly and thoroughly analyze a long memory acquisition and
calculate thousands or millions of parameter values, or find anomalous
measurements. A variety of views are then provided allowing quick and
easy measurement value understanding, as follows:

Histograms provide a view of the measurement parameter
distribution. See Create and View a Histogram (on page 96).

Tracks provide a time-correlated view of a measurement parameter
compared to other acquired channels or calculated math traces. A
common usage for track is to observe the modulation of a signal,
such as amplitude, frequency, or pulse width modulation. See
Creating a Track View (on page 103).

Trends provide a view of the measurement parameter over an
extended period of time and over multiple acquisitions. See Creating
and Viewing a Trend (on page 102).

Pass/Fail Testing (on page 103) allows definition of the normal or
abnormal measurement parameter value with a definable pass/fail
action alerting the operator when a condition is met.

WaveScan allows searching through a single acquisition for a
measurement parameter that meets a variety of conditions, or
scanning through multiple acquisitions with allowable trigger actions
when conditions are met. In addition, a variety of views can be used
to understand the specific behaviors of searched or
scanned measurement parameters. See Introduction to WaveScan
(on page 117).
These capabilities are only possible with the measurement of every
occurrence of a measurement parameter in a long acquisition.
Both Track and Trend are tools that can be used to plot measurement data
and observe variations with respect to time.
