Many people who do electronics as a hobby or in education (where funds are notoriously tight) don't need a high-end instrument but rather want something that is very affordable yet highly usable in practice. We offer a low cost USB Scope that is both powerful and affordable.

• Two input channels; many of the low-end scopes on the market have only a single channel which
  makes them little more than a toy - too often you need to display one signal with respect to an other
  (e.g. clock vs. data) and or trigger on a signal different to the one you want to look at.
• Triggering on either channel, rising or falling edge (selectable), or free running.
• Should cover the typical applications in a hobby environment - things like audio (0 - 20 kHz),
  ultrasound (< 200 kHz) and infrared (38 kHz), servo motor control (a few kHz), common data
  transmission protocols (RS-232, CAN, I2C, SPI, one-wire), so the analog bandwidth must be at
  least 1 MHz. This clearly precludes any sound-card based solution.
• Real-time Fast Fourier Transformation so one can use it as a simple spectrum analyzer, e.g. to
  look at things like distortion in an audio amplifier.
• Since the sample rate must be about 10x the analog bandwidth to allow meaningful display without
  very advanced filtering, it needs at least 10 million samples/sec.
• Fast and smooth acquisition - ideally it shows the signals "as they happen", i.e. with a screen
  update rate of at least 10 frames/sec.
• Needs a wide imput range form millivolts to volts.
• Low-cost and easy to assemble, so any moderately skilled hobbyist can build his/her own. 
• Small and easy to use so even a user without much experience with oscilloscope gets a quick start, and make it compact so it does not use much desk space.
• Uses USB to connect a computer as well as for power supply.
