I may need a Dual Mixer Time Difference (DMTD) instrument, to measure picosecond changes in electrical length in a coax plus amplifier time reference signal distribution system with total delays in the hundreds of nanoseconds, currently operating at 10 MHz (sinewave), but with 100 MHz likely at some future date.
What DMTD instruments are commercially available? A google search was not successful - all noise no detectable signal, probably because DMTD instruments are not that common, and many people build their own.
