Are you going to re-instate the battery option now? I find mine with the battery option fitted is great, it saves me having to turn on the entire bench feed if I just want to a quick and dirty ad hoc measurement, far quicker then getting a hand held DMM out. ![ThumbsUp :-+](https://www.eevblog.com/forum/Smileys/default/icon_smile_thumbsup.gif)
Unfortunately the internal battery measures a whole 206mV which means the cells are, to use a technical term, knackered. Thus I will look for something in the same form factor but it's going to come to about £40 after looking at RS. Not sure I can be bothered with that so might leave it disabled. I will do some research on suitable 6V 2.5Ah batteries over the next few days when I get some time.
Anyway calibration done and it's in situ now with its fellow emissive displayed friends (and other assorted cack)

Managed to fight the arduino and won by binning it and using vim + AVR-gcc + NT7S's Si5351 code. Also got the (cheap shitty) encoder connected to INT0/1 and run it on pin change interrupts as well. This only has one channel set up at the moment but I need two out of phase variable signals for a quadrature product detector and it's a pain in the arse doing it on the DG1022Z due to the randon phase alignment problems.

And on that note I'm going to turn it all off and go and watch Disenchantment in bed.
