Current probe amp for A6302

The AM503 Current Probe Amplifier allows display of current on any oscilloscope having 10 mV/div sensitivity, 50-ohm or 1-Mohm input, and (for performance to full bandwidth) at least 100MHz when using the A6302 (not included) or 50MHz when using the A6303 (not included). The amplifier attenuator has 12 calibrated steps in a 1-2-5 sequence, and the knob-skirt is illuminated to indicate current per division
