AM503B

Manuals – Specifications – Links – Pictures

The Tektronix AM503B is a current probe amplifier plug-in for the TM500 system.

The AM503B is an updated AM503A. It adds a third digit to the scale factor display, and support for the A6304XL probe.

For further details, please see AM503A.

The AM5030 is a TM5000 plug-in that is nearly identical to the AM503B with the exception of an added GPIB daughter board.
