I have used constant rate 1A peak for a lot of my testing. Lately been playing with bipolar Tx(not constant rate, time constant controlled), figure8 Rx. Noticed amplifier out decays thru zero during Tx. With constant rate it doesn't. Have read signal not decaying to zero during Tx subtracts from signal at Tx off(also think it's true). Wondering if signal that decays thru zero when Tx on adds or subtracts from Tx off signal.

What do you mean by decays thru zero? Is this peculiar only to your coil arrangement with the bipolar tx? Maybe it should shorten the time for target saturation on the flyback because it is the same polarity, therefore it adds? Not sure. -
Amplifier signal decays thru zero. Thought some more, not sure I remember correctly what constant rate signal did. Need to read https://www.geotech1.com/forums/show...501#post270501 again and connect constant rate Tx to try.Originally posted by dbanner View PostComment

Tried looking at constant current, constant rate and normal time constant Tx waveforms with spice with a US quarter as target. Constant current had highest signal(8% higher than normal Tx) and the highest average current(47% higher than normal Tx).Comment

If you look at the change of the target signal from the minus point to the peak, you will notice that it is about the same total.Originally posted by green View PostComment
