The Tektronix AM503A is a current probe amplifier plug-in for the TM500 system.

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.
