The PPS jitter is around 30nS most of the time, http://abelian.org/vlf/tmp/180225a.png The Octo sample rate is also staying quite constant too. The GPS has a poor view of the sky. The Octo is working well at 48k/sec. No feedback from the Flatmax Octo forum on the glitches at 96k/sec. Even if I keep the input level below 1.3V it looks like the S/N is poor. As it stands, it's not really usable at that rate. My LF rx project is stalled without a 3-channel 96k/sec capture. Later today I'll put the Octo back to 96k/sec for another play. -- Paul Nicholson --
