The AM503A and AM503B were updates to the original 1976 AM503. They have digital readout of deflection factor. The AM503S is an AM503A bundled with a TM502A mainframe, a TM-500 toolbox, and an A6302 probe.

The AM503, AM503A, AM503B, AM5030 and 11A16 use the same current probe input connector, an Amphenol 165-12 connector. It contains pins for hall element and transformer connections, lock detection, probe degaussing, and probe type encoding.

The AM503A and AM503B were designed by Mike Mende.

Output amplifier U171 in the AM503A is part number 165-2456-00.
