Hi,
I’m just wondering if it’s possible to find an external “unit” or “device“ for use as oscilloscope and possible spectrum analyzer for audio equipment (up to 100 Khz. would be sufficient) using an iPAD or even an iPhone as display/processor. I know there are lots of apps using the iPad’s microphone for this, but that is not what I’m looking form. I want a direct electric measurement from a circuit, perhaps even with 2 channels instead of one.
Did anyone make it this way? Can we buy it? Where?
Any sugestions will be highly appreciated!
Regards, Gerrit

Hi Rayma,
I’ve seen that one before, but it’s even more expensive than a basic digital scope. And it’s not a spectrum analyzer either.
I’m guess I could spend my $400 better than that.

Some of the good info is here:

Any compatible soundcard with the Apple Lightning to USB 3 Camera Adapter should serve as an interface.
Are there any PC/Tablet-plus soundcard applications that are suitable for/ capable of tracing hf oscillations in Opamp circuitry? I suppose a very wide bandwidth is necessary to expose those?
Tom,
I'm looking for anything up to 100 Khz.. I don't need RF detection, I can do that with other equipment.

Well, what is "any compatible soundcard". Compatible with what? iPad? I have a Steinberg UR242, but will it work? My iPad has no Lightning interface, it has USB C. So how should I make a physical connection?
This may be too complicated to be reliable and accurate. I need something that will work directly, every time when I need it, without having frustrating configuration problems.
I this a true serious option?

It's probably easier and safer to use dedicated hardware such as this one (randomly picked on Ali):

With iPad or even Android Tablet you may very quickly encounter connectivity issues with the lightning or equivalent connector which are fragile and not very reliable, at least for instrumentation.
If you really want to use your iPad, you can buy the new Rigol scope (DHO814), install a Wi-Fi dongle and get access to it on iPad with safari through Wi-Fi. But it's a bit more than $400.

UAC 2.0 compatible (https://en.wikipedia.org/wiki/USB#Audio_streaming).
Regarding your Steinberg UR242 see the manual on page22...
With Apple USB-C to USB Adapter it should work - UR242 is iOS supported.
