Example of AM stimulus output (600pps, fm=60Hz, depth=100%, 100μs pulse width, 10μs inter-phase gap, 1kΩ load, 600μA peak current). (A) Detail of a single pulse (B) A 20ms segment of the AM pulse train. The current spikes at the pulse onsets are over-emphasized by the oscilloscope sampling, and are minimal when driving a reactive biological load.
