I recently bought 4 older UBLOX GPS boards on eBay for $15 with free shipping. I hooked one up to my 1992 and comparing it with the Z3801, I am seeing it jump all over the place. I am using the 10 MHz output from the 3801 to start and the 1 PPS from the UBLOX to stop. I will have to bring in a TBolt just to verify the test set up. Has anyone here ever made any measurements on the UBLOX TIM-LF-0-000? These are not timing grade, by the way. The spec. sheet says the accuracy of the time pulse is 50 nSec. If that is +/- 50, then what I am seeing might be OK.
I would let the low-frequency PPS act as start and the 10 MHz as stop, unless you want to measure the PPSes directly.
