It's just a simple 3 wire capsule.

I am feeding the mic into an amplifier which will turn the signal into pulses. I want to measure the pulse width and compare the widths of the two mic inputs. The problem is I do not know what commands to use in the PBP program. I've read the manual and PULSIN seems to be a good command. I reallt need some hints on this. Thanks again very much for helping me even until this far.
