You know that is odd in the fact that the earliest pix of the oven shows 0.
Either its really 0 or seriously hot as the meter drives towards 0 from 50
when cold.
Typically lands about 30.

I shouldn't even be working on it my new tool box is still wrapped in
corrugated and is waiting for somebody to finish it. But I'm going nuts I
have to work on something so if I'm going nuts why not go time nuts :-)

How about just using an FPGA then? If you clock it at 200-400MHz,
then you can built a

Maybe I am missing something obvious here but after using the 1PPS/10MHz
reference multiplied up to 100 MHz cant you just insert a passive L/C
phase shift network at the input (or output) of the multiplier chain and
tune one of the "C" legs in the phase shift network to align the edges
Yeah when I get up this morning will start taking her apart and see what I
can find.

Hello,
My colleague Steve asked a question about wanting to generate a 10 MHz and
100 MHz squarewaves with both rising edges aligned to a reference 1 pps
input (to within 5ns).
We already have a product that can do this (at 10 MHz), but it is very
complicated, and Steve's job is to fine an
Pete just maybe the oven controller card went.
It would also effect the ionizer and that might explain the I beam jump in
the last seconds.
S the fact that the i beam went up may indicate there are some C's in
reserve.
On Frankenstein I built a new oven controller DC powered and run the tube C

You say "both," but which edge you pick is a little bit arbitrary
10 matches
