The schematic is much more useful.

I looked at the schematic and the attached is the area in the circuit where the chip resides. It looks to me like you will only have a pulse there when you have a target and it is moving. The pulse will only be there briefly, not steady.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

Well, it could but that's not what you asked about. You asked why you had no pulse there.

Tradução do português para inglês
Hello everyone, I would like someone from the forum can verify these differences between Delta and Pulse XR-71.
 The resistors are reversed and the transistors is an NPN and one PNP.
 Thanks ....
 Pray
