Re: [time-nuts] 5>10 doubler
Fri, Jan 30, 2015 6:35 PM
If you want absolutely deep notches, it is easy with the usual molded chokes to produce craters at 5 and 15 MHz that meet at 10 MHz, even producing some loss there. The harmonics are gone, then. At the -3dB point of a resonator we have 45° phase shift, now calculate how many ps delay that is at 10 MHz and then speculate on temperature stability.

Our data support that. Only 10% are really good.

Re: [time-nuts] PRS-10 PPS output

Why do I think that I am missing PPS from the PRS-10? Test 1. GPS PPS -> scope ch2 (1M input on BNC T) -> PRS-10 PPS in PRS-10 PPS out -> scope ch4 scope setup to trigger on ch2 PPS in and look 1.84us (200 ns/div) later at the PRS-10 PPS out. On infinite persistence, one clearly sees that some PPS out times remain at ground.
