Perhaps I stated this ambiguously. The 1.0KHZ pulse starts at the zero
line, or zero volts. One complete cycle is 1.0ms. The pulse starts off
at t=0. It takes a positive excursion to +5.0V for .50ms. It drops back
to 0V for .50ms and returns to +5.0V at 1.0ms. One complete cycle.
Does this sound like what you're describing? In any case I'll reconfirm
the signal into a 50 ohm load and if that works then I'll have my son
triple check his wiring. Thanks.
