New mixed-signal oscilloscope for iPhone, iPad and iPod touch

iMSO-104 is designed with a 5MHz bandwidth front-end and a 12MSa/s sample rate, simultaneously analysing one analogue and four digital signals for versatile, time-synchronised troubleshooting. All the usual input, trigger and maths features you would expect from a high-quality scope are incorporated, including cursor measurements, variable persistence, built-in 3.3V 1kHz reference signal and more. iMSO-104 also adds novel features such as computation power and instant emailing of screen captures. In addition, simple measurements of frequency, period, duty cycle, and reference signal capture are just a touch away. Timebase range is from 2uS-1S/div, with input voltage display from 50mV-2V/div. Maximum input voltage using a 10× probe is 40V.

iMSO-104 is based on Cypress Semiconductor's PSoC 3, a low-power system-on-a-chip mixed-signal IC, which handles Apple's proprietary dock interface for iOS devices while simultaneously processing incoming analogue and digital signals. The result is a scope system that is both affordable and portable. Intuitive finger movements are used to adjust trigger level, zooming, or repositioning channel displays. Captured signal screenshots can be rapidly sent as a time-saving email image for rapid reporting, Sent via other freely available Apps, current location and time can be included in the email with a link to Google Maps for logging on-the-job signal information.

Software for running iMSO-104 - including a demo package that does not require the actual iMSO-104 device - is available free at Apple's AppStore, and is available in English, French, German, Italian, and Spanish. iMSO-104 is compatible with all generations of iPod touch, iPhone, and iPad devices running iOS version 3.1.3 or higher. Set-ups can be customised and accessed quickly - great for on-the-go technicians. With these features and Apple's intuitive multi-touch user interface and high-resolution displays, iMSO-104 promises to deliver an easy and intuitive scope.
