Hello, thank you for sharing valuable comprehensive comparisions.
In the high timepulse rate experiment, have you also investigated other rates than the standard 10 MHz? Most Ublox receivers use 48MHz internal clock thus the 10MHz timepulse must be missing some of the clock pulses which generates additional jitter. 8MHz or 12MHz rates which are integer divisions might have cleaner output. .marek > On 24 Aug 2021, at 03:51, John Ackermann N8UR <[email protected]> wrote: > > In 2020 I did an extensive evaluation of the timing ability of the u-blox > LEA-M8F, NEO-M8N, NEO-M8T, NEO-M9N, ZED-F9P, and ZED-F9T.
