Oscilloscope Circuits

Calibrate scope jitter using a transmission line loop: 09/20/2001 EDN - Design Ideas / Digital-clock-period jitter is the variation in the period of a clock cycle compared with a nominal (average of many cycles) clock period.

Cross Trigger Two Oscilloscopes To Create a Delayed Sweep Display : 06/10/02 Electronic Design - Ideas for Design / Many oscilloscopes lack a delayed-sweep function. Plus, because typical users only occasionally require this function, simpler, more adaptable methods are worthwhile.

Delay line upgrades vintage scope: 04/18/2002  EDN - Design Ideas / Vintage triggered-sweep oscilloscopes find use in many applications. However, they have no internal delay line, so they can't display the pulse that triggers the sweep. Moreover, early laboratory scopes contain delay lines having insufficient delay to display such pulses during a uniform portion of the sweep.

NTSC Synchronization Separator: Stable Triggering of Oscilloscope Video Waveform Displays  Have you been frustrated by video waveforms which are difficult to display on your oscilloscope? Do you have to readjust the trigger level every Time the scene changes? This article describes a simple circuit that will allow a triggered sweep oscilloscope to provide the most important capability of a video waveform monitor, a stable display of the video waveform.
