I've installed an oscilloscope (oScope Lite) and a spectrum analyzer app (bs-spectrum). It would be handy to be able to get signals into the iPad directly (rather than via the microphone).

Does anyone one make a little buffer box to let you connect external signals without blowup up the microphone input on the iPad? Ideally it would have BNC connectors for scope probes and maybe an attenuator so you could input a range of voltages.

Thanks - Greg

Oh my that would be awesome! Let's join forces to find one. Deal?

I found this:

"The iPadís lack of audio line input support would appear to be a major limitation of the device, particularly for audio test and measurement apps. However, it turns out that the iPad can act as a USB host with support for 16-bit, 48 kHz USB Audio Class compliant devices. All you need to do is plug a compatible USB audio device into the USB port of the iPad Camera Connection Kit and youíre good to go."

That sounds very cool! I would think the App developers would be all over that option.

An adapter cable like this (http://www.kvconnection.com/ProductDetails.asp?ProductCode=KM-IPHONE-MIC&CartID=1) could be the start of an adapter but it is pretty pricey.

Here's a cheaper cable with the correct plug and bare leads at the other end: http://ca.mouser.com/search/ProductDetail.aspx?R=172-7436virtualkey11180000virtualkey172-7436

I have a soulution to add a microphone or accelerometer to the iPad. You can get the details on www.gtispindle.com or email me thoenig@gtispindle.com
I am currently using an app for full spectrum analysis for our company.
