App note: Real-time versus equivalent-time sampling

Saturday, August 2nd, 2014

Real-time versus equivalent-time sampling (PDF!), an app note from Tek: When a DSO uses equivalent-time sampling, it can acquire any signal up to the analog bandwidth of the scope regardless of the sample rate. In this mode, the scope gathers the necessary number of samples across several triggers. The input signal...

PIC32 oscilloscope

Tuesday, July 15th, 2014

Bruce Land writes: Turns out that the DMA channels on a PIC32 can move data from the ADC using the ADC done interrupt flag, but without wasting time in an ISR. The ADC can be triggered by a timer interrupt flag, again without software intervention. Doing this means that you...

Maker Faire 2011: Dangerous DSO

Sunday, May 22nd, 2011

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.
