[time-nuts] Another ThunderBolt cabling question

Acrually the PPS output has very low impedance, so you can probably load it with 5 instruments, each with 50 termination.

Not so for the 10MHz though

No you can't load the 10MHz (or the PPS) with five instruments in parallel.  You need a distribution amplifier.

About to do the permanent installation, if I bring two leads from the 10 MHz and 1 PPS BNC sockets on the TB to a panel in my shck can i have say 5 BNC sockets on the panel wired in parallel, with the lead from the 10 MHz socket on the TB feeding them all? And a single socket for the 1 PPS? Any need to screen the back of the socket panel, or enclose it in a metal box? Cheers.

Oh, I have been running lady Heather for a while tonight, here's a screen capture, does it look OK, ther's suddenly just two traces appeared? Thanks. http://www.chriswilson.tv/heather.png
