The A6312 is a DC-coupled current probe rated for DC to 100 MHz bandwidth, designed for use with the AM 503, AM 503A, AM 503B, and AM 5030 current probe amplifiers. Its split-core construction permits easy connection to the circuit under test, and it may be ordered either separately as the A6312 or as Option 05 to the AM 503S current measurement system.
A current probe clamps around a conductor to measure the current flowing through it without breaking the circuit, presenting the result as a voltage waveform for display on an oscilloscope. The combination of an A6312, an AM 503B, and a TM502A forms a current-measurement tool that can display currents up to 20 amps DC + peak AC and 50 amps peak pulse on any oscilloscope. Because the probe is DC-coupled, it measures both the DC and AC components of a current simultaneously.
ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Pre-owned instruments are inspected and functionally verified in-house before they ship, while new units arrive and leave factory-sealed exactly as received.
Tektronix was founded in 1946 and has operated under the Tektronix name ever since. The company was acquired by Danaher Corporation in 2007 and became part of Fortive Corporation when Fortive was spun off from Danaher in 2016.

Important: Maximum barewire voltage: 300 V (Category I).
Important: The A6312 is powered by the AM 503B/TM502A; the listed performance specifications apply to this combination of products. A current probe amplifier (AM 503, AM 503A, AM 503B, or AM 5030) and a TM502A mainframe are required to operate the probe and are not included with the A6312.
Important: For the A6312/AM 503 combination, the specified risetime and aberrations require adjustment of R364 (HFComp) in the amplifier.
