Delta Pulse - Take 2

[kt315]

first of all i congrut you that you have original LF357 or one near it at least.
yes, because you see the ripple. it is sure indicates opamp has needed slew rate.
yes, with 40us min first delay this ripple will not affect operation. but some people want to rretune
DP to 10us. then they have to pick up the overdamping resistor value more precisely, decreasing in low side.
in original DP circut it is 1.1 kOhm. yes, 1.1 k, i do not lie.
i do not write nothing new. that is standart understanding in PI and you can find that in
any threads related PI.

I have this ripple on the output of lf357 and i don’t know how to fix it or if it is normal. The other photo is the signal acros coil leads and looks good. In my opinion will not affect operation because is in the first 10uS and i never use that delay for this type of detector. What do you think guys? Many thanks!

DP files archive has to be deleted today. i will refresh it.

DP?Has anyone ever made this? What's the actual effect? Do you have any pictures about it?

Hi KT,
It's been almost 3 weeks, and no PCB. Just wondered if you have a tracking number for the parcel?

what is progress Jim? pleasure.

Is there a BOM or parts list for the specific schematic?

he attacked my mail box by spam messages with his boring approvals that PI on micro based is good, while analog is bad.
i answered that i do not do micro's PI. no emails after that.

You did smarter than i did.
