Hi all. I'm looking for some help on cleaning up prox probe key phasor signals to make them more reliable for one of my monitoring systems. Basically, one of my analyzers really wants a pure TTL signal and has a hard time with a "real world" prox probe based key phasor signal.
In the "old days" of FM tape recorders, we used to use a set of amps/filters to get the recorded signal up high enough to work with various analyzers. It was long ago and I don't remember the manufacture of those amps.
I'm hoping someone out there has already figured out a clever way to clean up a prox probe key phasor to be more compatible with "modern" analyzers. I know there are a few of the newer analyzers with this same issue. I'd appreciate any input on this. (I'll save the rant about why any modern analyzer mfg would sell an otherwise excellent system that won't work with the intended market's systems)

A Bently TK15 will do what you want. See attached.
