| The Huntron Tracker was introduced in 1976 as a way to troubleshoot down to the
component level without applying power. Technicians and engineers worldwide have learned
that Huntron Trackers are an indispensable tool that can detect problems where other
methods can not. Trackers work by applying a current-limited AC signal across two points
of an electronic component. The reaction of the component to the AC signal produces a
unique voltage/current (V/I) signature. Using this signature information, experienced
troubleshooters can isolate faults on bad boards by comparing to good boards.

Variable ranges allow you to select the specific voltage, resistance and frequency of
the test signal. This capability enables you to tailor ranges to a specific type of
component family (i.e. TTL, CMOS, low voltage logic, etc.), screen out an unwanted portion
of a composite signature and document the exact voltage, resistance, and frequency in a
test procedure.

Huntron complements conventional test
equipment with access and test tools that catch the elusive problems other
methods often miss. The keys are physical and virtual access, which translates into meaningful
results such as shorter design cycles, improved production yield and lower
warranty costs. When you need to test, diagnose or troubleshoot complex
circuit boards, Huntron lets you access, explore, and discover more.
