Testing of analog circuits

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Arrangements for testing electric properties; Arrangements for locating electric faults; Arrangements for electrical testing characterised by what is being tested not provided for elsewhere > Testing of electronic circuits, e.g. by signal tracer > Testing of analog circuits

CPC:

Arrangements for testing electric properties; Arrangements for locating electric faults; Arrangements for electrical testing characterised by what is being tested not provided for elsewhere ( testing line transmission systems H04B3/46; testing or measuring semiconductors or solid state devices during manufacture ) > Testing of electronic circuits, e.g. by signal tracer ( testing for short-circuits, discontinuities, leakage or incorrect line connection G01R31/50; checking computers G06F11/00; checking static stores for correct operation G11C29/00 ) > Testing of analog circuits

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1995.
