The first oscilloscope I ever used professionally was an old synchronized sweep instrument. Obtaining a stable display on that old oscilloscope was an art. Now I appreciate all the triggering tools available on even the most basic oscilloscopes.
An oscilloscope trigger synchronizes the oscilloscope’s timebase to the input signal, producing a stable display. In analog oscilloscopes, the trigger initiates the sweep generator so that the horizontal sweep is synchronous with the vertical signal. Digital storage oscilloscopes (DSOs) produce the same effect through a different method. In DSOs, the digitizer runs continuously and the trigger event marks the associated data in the acquisition memory, locking the signal data for display, measurement, and further processing.
Today’s DSOs include relatively simple edge triggers, more sophisticated “smart” triggers, and still more complex “augmented” triggers. Let’s look into these multiple trigger implementations.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
