                                    The Tektronix TR 210 is an accessory to an oscilloscope
which allows power off
troubleshooting of electronic circuits by using the
technique of Analog Signature
Analysis.
This signature shows the V/I characteristics of an
electronic device which when
compared with a known good device, can assist in locating
faulty components of
a circuit without applying power to the board under test.
This technique of
troubleshooting simply involves the visual comparison of
circuit signatures
which can assist in isolating circuit failures due to opens,
shorts, device leakage,
ESD damage, power supply over-voltage and transients.

Analog Signature Analysis or ASA is a unique, power-off
troubleshooting
technique. It uses an alternating current (AC) sinewave
stimulus to show the
current (I) vs. voltage (V) characteristic of an unpowered
component on a CRT.
The IV characteristic is called an analog signature and 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. You can compare
signatures of suspect
components to signatures of known-good components.
Test current applied across a component is limited. When
used carefully, this
technique is non-destructive 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.
■
 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.
