Educational experiments

The Pico Technology library of science projects contains a number of educational experiments suitable for use with our oscilloscope and data logging products.

If you are involved in the teaching of science we would love to hear from you. We are looking for people willing to perform and write up new experiments for this collection. For a limited time Pico Technology is willing to donate a DrDAQ data logger in return for a suitable experiment. For more details on this, please read our guidelines on submitting science projects.

4 channel differential oscilloscope

See the difference with the new PicoScope 4444

With four true differential channels, the PicoScope 4444 enables high-resolution measurements of differential voltage waveforms. This oscilloscope eradicates the problem of making accurate voltage waveform measurements on circuit elements that are not ground-referenced, without the risk of short circuits that could damage the device under test or the measuring instrument.

  • 4 channels
  • 20 MHz bandwidth
  • Flexible 12-bit or 14-bit resolution
  • Up to 400 MS/s sampling rate
  • 256 MS capture memory
  • High common-mode rejection ratio
  • Balanced high-impedance inputs for a low circuit load
