If we build this circuit it would be a bench model not designed to be inside a hot chassis. It would be able to lock ± 5° C of 25° C. My idea of an oven is to keep the crystal and oscillator at 25° C ±0.001 °C with 60 second warm up/cool down time. πθ°μΩω±√·Γλ WB0KVV ---------- Forwarded message ---------- From: Bob kb8tq <[email protected]> Date: Fri, Jun 2, 2017 at 5:57 AM Subject: Re: [time-nuts] HP5061B Versus HP5071 Cesium Line Frequencies To: Discussion of precise time and frequency measurement <[email protected]> Hi I would suggest you check a few real crystals over the 20 to 40C range …. With all the “stuff” in a 5061, it will change (rise) at least 10C after turn on.
