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.

Rear interface

The output can be detached from the front panel BNC socket which has a Peltola connector on the inside, and re-attached to a Peltola socket near the top of the interface connector, where it is terminated in 50 Ω and brought out on pin 28A (ground on 27A).
