8-6 Timing: Using the Analyzer
The section describes how to select one of the two analyzer modes
and the sample period or rate.
The Timing Analyzer Softkey Interface has two modes: standard
and glitch capture.

Standard Mode

The standard mode is the usual data acquisition mode. In this
mode, all sixteen probe signals can be analyzed and 1010 samples
can be taken. This is the default mode for the analyzer.
The commands
display trace_specification
mode_is standard
change the mode to standard.

Glitch Capture Mode

The glitch capture mode is used to detect and display multiple
signal transitions between data samples. If more than one
transition is detected between samples, the information is stored in
a portion of trace memory reserved for glitch information and is
displayed on the screen. A glitch is displayed as a broken vertical
bar or a series of broken vertical bars depending on the
magnification. (In ASCII diagrams, the default symbol is a colon
":".) A vertical bar also indicates the occurrence of multiple data
transitions too close together to be displayed at the selected
horizontal magnification.
The command
mode_is glitch_capture
sets the analyzer mode to glitch capture.
