Convert Analog Oscilloscope into a DSO (aka webCam Oscilloscope)
Demonstration of "converting" an analog oscilloscope into a digital storage oscilloscope. The "poor man's" version !
"Webcam Oscilloscope" is software that uses a webcam connected to a PC to capture video and images from analog oscilloscopes. The video and images can then be analysed using on-screen cursors for typical Digital Storage Oscilloscope (DSO) functionality.
The software and instruction manual are available for free download at:

The software has the following capabilities:
1. Utilise any webcam connected to a PC to capture video/images for DSO type analysis
2. Store captured video/images from an analog oscilloscope to hard drive (as .avi or .jpg) - annotated with user selected calculated waveform data
3. Provides voltage and timebase controls for two channels
4. On-screen cursors for delta-time, delta-voltage (auto calculation of frequency)
5. Calculation of duty cycle, phase difference and rise time of waveforms on captured images
6. Calculation of capacitor and inductor value from captured waveforms using a frequency generator with the DUT
