Fault Diagnostics in Power-Off State
QT55 - Qmax Test Technologies Pvt. Ltd.
Signature Method of Testing is also known as VI Trace Characteristics, is a proven fault diagnostics technique in Power-Off state while testing a board. By applying known wave from signal with desired Voltage, Source impedance and Frequency of the stimulus signals, depending upon the test node and its characteristics, a Voltage (V) vs Current (I) graph is plotted and studied.
