Is his really interesting?

I agree, it's a good chunk of money, IMO for the features it's worth the cost, it's got 14 bit resolution on the 100Msps ADCs, DACs, plus 100Msps 16ch logic in/out. It's like a little Swiss army knife, with some patience it will do most jobs, but it can not compete with a dedicated instrument at any specific task.

And of course, like any instrument, it's only worth it if you got a use for it, like e.g. you don't already have an arbitrary function gen or you don't already have a logic analyzer/generator or high res scope, low frequency spectrum analyzer or network analyzer etc.

If it's just another toy that will start collecting dust after a week, then it's probably not worth the money :)

Last feature for now, I think, input impedance measurements:




Then I just need to clean it up, do a bit of testing and bug bashing.

Looking forward to the release of this software jaxbird. Then I'll get an AD.

Excellent work.

Hey, how hard is it to do a "normalize"... i.e. the software takes a base reading, normalize it to flat response, then put the DUT, and let the software do it's thing (relative to the normalized base reading)?

Thanks, but you should only invest in the Analog Discovery if you really feel you have a use for it, no obligations :)

I'm putting a lid on new features until a release is available, after that I'll start tracking bugs and feature requests.

I've been preparing the software for distribution, primarily to make it easy to distribute and update, so I've gone with a web deployment strategy with update check on startup. It will still run fine offline, but if online and there is a new version available on startup it will suggest to update. Not that I expect it to be full of bugs, but I'm sure there will be many updates initially so easy updating is fairly high priority.

Also it needs a bit of explanation on how to configure connections for the various measurements, some measurements require various shunt resistors. So I'm compiling a document for reference and perhaps a video.

Anyway, I expect to have an install ready within the next couple of days.

Made a couple of minor changes:

The power vs THD+N now includes the input level. It's nice to know what input level is required e.g. when clipping occurs. I'm considering adding a scope view as it's nice to know the balance, as in, if one rail is clipping prematurely.



Also, I've referenced the frequency response at 1kHz level by default, it will still show the voltage gain at cursor position:




Release will be shortly after Christmas (once I get past the traditional hangover :))
