Mac the Scope uses the line inputs on a mac and functions pretty well as a high bandwidth oscilloscope.

Very nice, but we will need to able to measure DC. I assume the audio inputs are AC coupled?

I don't know offhand, but I believe you are correct in that assumption.

The Labjack is made by a smalll, windows only outfit, but they have been very helpful to people interested in getting drivers working on other platforms (like the mac and Linux)

These DAQs will be used in a course lab and will have to be supported by university staff technicians. They will not be happy if I select hardware without "official" support. That's just the way it is here. If it were for my lab, I would have not problems with relying on "community" support.

Ah, now I see. Sometimes community support can be better than from a company. Linux vs Windows anyone? ;)


I can tell you that the LJ kext "just works" but also, if you're going to use a LJ on a Mac, you're going to have to roll your own software for it as well. This is also a consideration. I have a few applications that I've done for it for which I'd be happy to share the source code...

If you're going to be using this stuff in a simple undergrad lab course, I would give the Pasco stuff a good hard look. They have over a dozen types of sensors, software to go with it, and it does seem much more suited to this kind of a scenario.
