Tektronix AM 503 Highlights
The AM503 Current Probes convert the DC and AC flux field of a conductor to a voltage signal which is sent to an AM503B or AM5030 Amplifier. The probes include both a Hall Effect device, which senses the DC current, and a ferrite transformer which senses the AC current. The probes also utilize a bucking current from the Amplifier, which eliminates core saturation. The bucking current is 20 A for the A6302XL, 100 A for the A6303XL, and 500 A for the A6304XL.
Requires a TM500 or TM5000 Series Mainframe. Allows display of current/division on an oscilloscope with 10mV/div Sensitivity, 50 Ohm or 1 Megohm input, with at least 100MHz bandpass.
