Hello , I have a z3801 and trying to use the 1 PPS from the rear panel for the start input of an HP5370B This approach seems to work fine until a load is either added or turned off on the same AC circuit or a nearby circuit.
At which point the hp5370 takes a hit and a trace that had been running ok drops back to 1x10 -3 or ... When using 10 Mhz or 100 Khz as the start input this does not happen. The connector on the back of the z3801 is in a format Pseudo ECL and I don't think it uses a ground as a reference. Is there a simple one transistor buffer that I can use, build it right inside db 25 shell? Or maybe there is a different approach? I am using a shielded coax to transport the 1 PPS but at the 5370 of course it is grounded but not at the z3801a Thank you for the help Paul A.
