The A6312 is a 100 MHz DC-coupled current probe for use with the AM503, AM503A, AM503B, and AM5030 current probe amplifiers. The combination of an A6312, an AM503B, and a TM502A provides a flexible current - measurement tool that can display currents up to 20 Amps DC + peak AC and 50 Amps peak pulse on any oscilloscope. It has a split core construction that permits easy connection to the circuit under test. It may be ordered either separately as the A6312 or as Option 05 to the AM 503S.
