Good Initiative but the price and spec does not match

This is a good initiative to use the available hardware for test and measurement, but it is not supporting the need of any one, as a hobbyist will not be able to spend this much and the frequency range is too less for a professional use, it fact it would be better to write a code to accept usb samplers on iPads/iPhones.

If all different functionality (e.g. low bandwidth spectrum analyzer etc) is at $300, this will be very attractive.

_hm, I agree that the price is high. Oscium has made other products using the same or similar hardware, that being a logic analyzer (8 channel) and a WiFi spectrum analyzer.

These type of Test and Measurement instruments are good. But I have following suggestions:

This will be generally used by hobbyist beginner. For them, this may be too expensive. Price should be below $100.

Software/hardware together should make it possible to use the same device as DMM, FG, Counter, oscilloscope, volage source, current source etc.

it always comes as an unpleasent surprise when I realize I'm not using a touch screen.

An engineering first-world complaint if I ever heard one.

@elctrnx_lyf, I think we will see more wireless-controlled test equipment using phones and tablets. Personally, I'd like a bench oscilloscope with a tablet for a screen and you can detach the tablet when you need control from a distance.

Agilent's feature-packed DSOs/MSOs use tablets for display and control

Seems like another era of test and measurement is going to start with these new devices. But I'm not going to get these so early.

Digilent make the Analog discovery, a scope / waveform generator / logic analyser for PCs via USB.   Similar specs, 5 MHz b/w, 16 logic channels, spec analyser....

Not sure if it will work with any tablets...maybe Win 8 tablets if they have USB?  But not with Apples......

Details here

and more here

I've used the NI MyDAQ which is similar but has a paltry 200ksps (= not much more than 20KHz) bandwidth - I'd much rather have one of these!

Here's a link to my review of the Link Instrument MSO-19.

I have a Link Instruments MSO-19 to use as a comparison. Truth is if I need ascope and the 5MHz bandwidth isn't a limitation, I'll surely use the Oscuim over the lin just because I can use it on my iPad or iPhone. The Link DSO requires a laptop.
