I discover that I am in posession of a WJ-8716 which happens to have a BNC on the back for an external 1MHz reference. I also have a Z3801A that makes 10MHz. Is it as simple as turning the 10MHz PECL into TTL, dividing by ten (e.g. 7490), and feeding this into the WJ-8716?
The WJ-8716's internal frequency standard is already pretty good (at the very low ppm level from turn-on through warm-up) but I still want to give this a try. What other common (that is, consumer or floating around on the surplus market from the past couple decades) rcvrs/xmtrs/transceivers can be slaved to external frequency standards? Any potential evil (phase noise?) that may come about from using a junkbox 7490 divider? Does most equipment care whether I do the divide- by-five first and then the divide-by-two, or are they happy with the funky waveform out of the divide-by-five?
