I plan to keep BVA powered. My question was how do you accomplish this and what do you do it with? I've been using PS like for example Fluke PM2811, Tekpower TP3005T, Dr. Meter HY3005F-3 (these are similar), Sorensen and some older HP. I've had good luck them all so far. I'm curious if someone's found some better way that's smaller and newer and still good? It looks like a big UPS is in my future. Luckily I rarely have power outages here even in the desert of the southwest in AZ where the temp and even humidity is mostly stable inside in the AC in summer and even heat in the winter. It's dry in both cases inside in my lab.
Do you monitor the thermistor along with the frequency and external temperature/humidty? I've been using this for external: http://www.dogratian.com/products/index.php/menu-sensors/menu-usb-pa-type-a-bmp085 It seems to work pretty well to monitor temp and humidity with USB for the room plugged into my computer. What I'm starting to think about is how do this on much larger scale at the same time? I have a few counters 53131, 53132, CNT-90, and an SRS SR620 but how do you do long term measurements over long extended periods on multiple powered up oscillators? Is there a mass way to do this? I know the computer could handle this with GPIB but is there another better way to say monitor all these variables on say 5 to 10 DUT constantly easier? I have an HP3458A but I wouldn't want to keep it tied up too long. The counters I run a lot so that's not a problem really. What do you orchestrate the whole thing with? I have labview NXG but I'm not sure some hardware DAQ or something with some scripts might not be better for multiple DUT than messing with labview running all the time. How do you do it? How do you get stats on multiple oscillators for years? I suppose some oscillators deserve their own dedicated counter 24*7 and maybe even a raspberry pi to sample the GPIB. I do have a few USB to GPIB interfaces and Pi's are pretty cheap but I've only got a 2 and a 3 right now. But then is there a timelab for Linux? I suppose the first main key is to just keep all the OCXO and GPSDO's powered all the time first on a UPS?
