Hi,
If I want to add a data logger interface to a PI detector, e.g. the Hammer Head circuit, at what point should I best tap the signal for the data logger interface circuit? Immediately after the preamplifier? Or perhaps before the audio circuit? An operational amplifier for buffering the signal and an optocoupler stage are intended for the simple interface circuit.
Does anyone perhaps already have a circuit that can be used?
