I think one day soon, if not already now, somewhere, there will be Multimeters that have touchscreens and are software configurable with Apps that allow you to add most anything to your meter like an O-Scope, function generator, logic analyzer, etc. and a way to configure inputs and outputs and test sequences to use for specific testing circumstances. And if your repairing a certain type of device you can upload your test sequence so that others can follow your process and steps with things like "put the leads on this component press test" and it compares the results to your pass/fail requirements along with pictures and so on, so you can do this on site. Companies can send out the complete steps to troubleshoot their gear that are downloaded and put into your meter so that all you have to do is follow along to find the problem. With that in mind, is there a particular development board and software out there that can handle something like this? I think the touchscreen part is out there but I need something that has specs like National Instruments multifunction PCI card that is built onto the development board, or an add on board, or could someone smarter than me make something like this ASAP?
