08:12 <hartytp> rjo: one other thing related to servos

08:13 <hartytp> In the long term, I'm sure Sayma servo will get funded and be very good. But on the shorter term, we have some concerns (as previously discussed)

08:14 <hartytp> ranging from complexity of the JESD204B ADC; to the difficulties of getting users to agree on a specification; to the difference between our "PI amplitude servo with profiles" desings and the more complex (demodulation etc) plans currently on the wiki

08:15 <hartytp> so, we're looking for a "plan B" for Sayma as well as Urukul, which should get us going in the lab for the short term (next year?) until a proper solution is worked out

08:16 <hartytp> The best option I came up with was Novogorny connected to Sayma AMC FMC (FMC to VHDCI adapter + VHDCI_carrier)

08:16 <hartytp> then use a modified version of the Urukul servo, multiplying the SAWG amplitude rather than the DDS amplitude

08:16 <hartytp> a bit ugly, but should do the job

08:17 <hartytp> I'm not sure that there's anything you need to do about this directly -- it may end up being a hack that we kludge together in house

08:18 <hartytp> but, it would be good to keep this kind of use case in mind while designing the Urukul servo to maximise possibilities for code reuse

08:18 <hartytp> Oh, and a second thing: cjbe has already written an artiq applet for our current noise eater.

08:19 <hartytp> Not sure if it's a help, but ping him if you want to see it

08:20 <hartytp> (in case you feel it'd be helpful for you to see how we use our current servo in the lab/what our current GUI looks like/etc)
