System Performance Analysis (SPA) Software

System Performance Analysis Software

The System Performance Analysis (SPA) software is included as

standard software in the 1670G-series logic analyzers.

SPA provides you with a set of functions for performing statistical

analysis on your target system. Its functions include State Overview,

State Histogram, and Time Interval modes.

To be successful with this software, you should be familiar with the

operation of the logic analyzer.

This chapter is organized as follows:

• "What is System Performance Analysis?" outlines typical SPA applications,

and describes the operating characteristics for each SPA mode.

• "Getting started" describes how to access the SPA menus and how to select

the SPA modes and set the specifications.

• "SPA measurement processes" is a detailed description of the

measurement processes used by the SPA package. This theory of operation

explains how the SPA software samples and sorts the data from the target

system, and how the onscreen measurement values are computed for the

State Overview, State Histogram, and Time Interval modes.

• State Overview, State Histogram, and Time Interval" leads you through the

State Overview, State Histogram, and Time Interval modes. It also tells how

to set up SPA for the three modes, how to interpret the acquired data, and

how to make measurements on specific areas of interest.

• "Using SPA with other features" tells you how to use SPA with other

features.
