Appendix C – Analysis Test Circuits
The DCA Pro analyses components by applying signals to the
component under test while in a “test circuit”. The test circuits that the
DCA Pro uses to analyse various components are shown below.
These test circuits are presented here to assist in your understanding of
the test conditions that are possible when testing in standalone mode
and in the PC mode (for curve tracing etc).
Transistor Test Circuit
Example shown is for an NPN transistor. Polarities are reversed for
PNP devices.
