An example of a QFP (64 pins), this was done by defining only 8 locations (Pins 1,16,17,32,33,48,49 and 64): 24.001 / 13 June 2024...

    ASA101A User Manual support@electron.plus ..5.7 Common/Grounding importance Analog signature analysis relies on examining the voltage vs current signature between two points in a circuit. In most circuitry this is between a supply rail (typically 0V) and the point-of-interest, however it doesn't have to be so.

    ASA101A User Manual support@electron.plus ..5.8 Capturing Golden signatures Capturing 'golden' signatures should happen AFTER the test file has been setup and the test points have been chosen. Capturing signatures can be done either singly ("Single Capture") or automatically ("Auto Capture").

To stop this, deselect the V/R/Hz checkbox on the Test Controls area. When you have finished a test, you can save the file. This will save the results of your test and is useful for review at a later date or as part of quality control etc.
