--Jim Stone Hi Bob, Take a look at this nice simple little one chip "TDR" and lesson on how to use it to measure cable length and cable impedance. It uses a single AC14 (can use a DIP so no SMD needed) and gives a nice crisp 2 or 3 ns rise. The AC family is nice fast logic and has been us

Re: [time-nuts] Austron 2010B (disciplined OCXO) square wave conversion

I don't have the manual but I'm sure if you pop the cover you can find a nice sine wave inside (that is being converted to square wave). Un-solder one of the square wave output BNCs and patch in the sine wave. Now you have analog and digital outputs!
