Just to rule out any issues with the Siglent, even though it had been recently checked against cal standards and was locked to my lab 10 MHz distribution system, I directly measured the 10 MHz outputs from my SRS FS752 GPSDO and my Symmetricom rubidium standard with the ThunderScope. Both showed 10.665 MHz, while in reality they were both 10.0000000000 MHz give or take about 2e-11. So the Siglent was fine, and the ThunderScope’s timebase was 6.6% slower than it should have been.
