Section 1 Introduction
1-1 What is a Tracker 2800?
A Huntron Tracker 2800 is a troubleshooting instrument that is used manually to troubleshoot printed
circuit boards to the component level. Throughout this manual it will be referred to as the Tracker 2800
or 2800S (where applicable). This instrument uses a troubleshooting technique called Analog
Signature Analysis (ASA) for applying a current limited sine-wave voltage to an un-powered circuit or
electronic component. The resulting Current (I) and Voltage (V) characteristic (analog Signature) is
then displayed and used for comparing known good signatures of a good circuit card or electronic
component to those of a suspect circuit board. This comparison allows you to troubleshoot circuit cards
and electronic components without applying external power or requiring circuit cards to “start up”.
Each pin of a component can have a unique signature. When components fail, their signatures change
so troubleshooting using ASA is simply a matter of finding the defective component by analyzing its
signature. The Tracker 2800 implements the ASA technique of troubleshooting.
The built-in current limited stimulus sine-wave of the Tracker 2800 ensures non-destructive testing and
does not damage any components. ASA has many advantages as a proven, fast, and effective
troubleshooting technique.
You can:
Troubleshoot circuitry that cannot be powered up due to a shorted condition.
Troubleshoot in a qualitative mode, allowing you to see physical problems with a suspect component.
Compare device characteristics with known types for better matching.
Investigate intermittent problems by seeing marginal indicators, such as small amounts of leakage,
noise, etc.
Eliminate risk of accidental shorting across other points during POWER ON testing which could
further damage the component or other components on the board.
Minimize the risk of shock hazard since the ASA troubleshooting approach requires no power applied
to the circuitry.
Perform preventative maintenance by seeing flaws in components that could possibly lead to untimely
failures.
Look at replacement components before they are installed in circuitry to reduce the risk of installing
defective ones.
