Have you seen one of these? http://www.seeedstudio.com/depot/dso-quad-aluminium-alloy-black-p-1034.html?cPath=174
DSO Quad is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks. It's based on ARM cortex M3 (STM32F103VCT6) 32 bits platform, providing 72MS/s sampling rate with integrated FPGA and high speed ADC. Internal 2MB USB disk could be used to store waveform, user application and upgrade firmware. Handheld DSOs have been around for a decade or more, but until fairly recently they've been over $1000 (see Fluke's Scopemeter family). In recent years there have been a few low-end scopes as kits or products in the sub-$300 range (Vellman (vellemanusa.com) makes a few), but the low-end specs make them useful for not much more than audio frequencies. There also have been computer add-on products for creating a DSO on the cheap. First peripherals for desktop computers, then laptops, and now iPhones. They all look pretty clunky to use. Now it appears the commodities spilling over from volume production of smartphones is making self-contained handheld scopes relatively cheap. The 2-channel (the 4-channel claim is misleading) 72MS/s DSO with a color LCD in a package about the size of a smartphone sells for about $200. These seems to be popular with hardware hackers. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
