Sqkybeaver let us know Sparkfun now carries a scope similar to the one he reviewed. It is a two channel 100MHz digital scope with 500MSa/s real-time sampling rate. Saving waveforms to a USB flash drive is available, as well as interfacing with the computer over the USB port. The waveforms and menu are displayed over a 5.7″ LCD Screen. Via the forum.

Maker Faire 2011: Dangerous DSO
Dangerous DSO is a new logic analyzer/oscilloscope prototype we’ve been using in the lab. It combines a 16 channel logic analyzer with one 50MHz oscilloscope channel with +/-10volt DC range. The combined tool shows what your signal does between 0 and 1, which helps pinpoint noise and other electrical glitches.
Dangerous DSO part 4: Over simulated
Yesterday we covered the Dangerous DSO analog front end. This circuit divides our +/-10volt input to +/-0.5volts, and re-centers it between the 2volt and 3volt range the ADC can measure. Today we’ll simulate the circuit to get a better feel for how it works. Dangerous DSO is a new logic analyzer/oscilloscope design we’ve been using […]
Dangerous DSO part 3: Messing with the front-end
Yesterday we looked at how the Dangerous DSO analog to digital converter works, and it turns out to be a pain in the butt. It only measures a 1volt (1Vp-p) range between 2volts and 3volts. That’s not a very useful range for an oscilloscope, so we need an analog front-end that transforms the input signal […]
Dangerous DSO part 2: Feed and water your ADC
Dangerous DSO is a new logic analyzer/oscilloscope design we’ve been using in the lab. This is not a finished project, it will not be produced. We’re posting our current progress to get some feedback. Look for a new Dangerous DSO article every day this week. Be sure to see Part1: There’s so much between 0 […]
TOOLS: Atten ADS1062CA oscilloscope
Our favorite tools have a new home on the wiki. Each week we’ll muse about one of them. Have your own tool review? We’ll post that too! The Atten ADS1062CA is a dual channel digital storage oscilloscope capable of 1Gsamples a second, and an analog bandwidth of 60Mhz. An oscilloscope is a useful piece of […]
