Just for fun

SS-5100DS1B oscilloscope, in your browser Beta

Turn the V/div, time/div and trigger knobs. Look at a sine, a square wave, switch-mode ripple, or your own voice through the microphone. Then try the classic mistakes: a wrong probe setting and a badly compensated probe.

Beta, just for fun. This is a playful beta, for illustration only. It is not a training tool and not a substitute for the real instrument. The actual SS-5100DS1B can differ in appearance, display, button behaviour, ranges, timings and readings. Everything here is simulated, so do not use it to judge a real measurement. Always follow the instruction manual and your site safety procedure.

How an oscilloscope works

  • What you see: a graph of voltage (up) against time (across). The grid has 12 divisions across and 8 up. The V/div knob sets how many volts each square is worth; the time/div knob sets how much time each square is worth.
  • Trigger: the scope waits until the signal crosses the trigger level in the chosen direction, then draws from that point, so a repeating signal lands on the same spot every sweep and looks steady. Move the trigger level outside the signal and it loses sync: Auto mode then free-runs and smears, Normal mode waits and keeps the last picture, Single catches one event and stops.
  • Coupling: DC shows everything. AC blocks the steady part so you can zoom in on small ripple riding on a big DC level, like the switch-mode supply output. GND shows the zero line.
  • Probe setting: a ×10 probe divides the signal by ten. If the scope is not told, every reading is ten times too small. Set the scope to match the probe. That single mismatch is one of the most common scope mistakes.
  • Probe compensation: a ×10 probe has a small trimmer. Connect it to the scope's square-wave test output and adjust until the corners are square. Rounded corners mean under-compensated, a spike means over-compensated.
  • Clipping: if the signal is bigger than the screen, the scope clips it and the measurements are wrong. The simulator marks clipped measurements with a star.
  • Bandwidth: the SS-5100DS1B is a 100 MHz scope (−3 dB), and a ×1 probe is limited to a few MHz. Push the function generator to its highest frequencies and watch the amplitude fall.

This is a playful beta simulation. The signals are idealised, the front panel layout is simplified, and the real SS-5100DS1B has more controls, menus and 32 automatic measurements. The test source, probe behaviour and microphone input are simulated or illustrative. Your microphone, if you choose to enable it, is processed only inside your browser and nothing is recorded or sent. Always follow the instruction manual and use correct, rated probes on live circuits.
