Hi Your dac voltage is still swinging 20 to 25 mV over the period (4 to 5 divisions at 5,000 uV per division). It tracks the temperature as reported by the sensor just about 1:1 (yellow and green lines follow each other). It still looks like your OCXO is moving around quite a bit with

I'm weighing in a little late on this one but wanted to make a few comments regarding cables and connectors in hopes that a prior poster may not have covered these thoughts. With regards to single-shield coaxial cables, I think we are all aware that shielding effectiveness can vary widely

Thanks Bob, My first run I had an 80mV and 2.5C swing and after some improvements I have a 23mV and 1C swing. So I was able to make things better but clearly I have a ways to go. The 136 second holdover was because I opened the oven to make some changes but didn't reset Lady Heather for a
