Measurement System
provides a complete system
in a single package. It consists
of an AM 503B Current Probe
Amplifier, a current probe
(A6302 is standard, A6312 is
Option 5), a TM 502A Power
Module, and a plug-in toolbox.
You can boost flexibility by
using any of the four other
A6300 Current Probes.
The AM 5030 Current Probe
Amplifier is a GPIB programmable version of the AM 503B;
use it with a TM 5000 Power
Module and any of the six
A6300 probes to extend your
capabilities.

Note:
The AM 503B works with a TM 500 or TM 5000 Power Module,
the AM 5030 plugs into only the TM 5000 Power Module.
XL Probes work only with the AM 503B and AM 5030—not with
the older AM 503 and AM 503A Current Probe Amplifiers.
