Hi
My board is self etched HH revc option 1
I am hoping someone can tell me if these oscope readings look OK. I have the pulse width set to min. on R3.
On TP1&TP2 photo, If I am correct that would make the pulse width about 200us.
The horiz position is set to 50us/div and probe set to 10x.
On the other 2 photos I am wondering if the two spikes on TP4 should be there. They seem to have something to do with main and secondary samples.
Regards
Peter
