Testimonials

  • The kit (2408B) is of obvious quality, easy to setup and calibrate and the free to download software has a reasonable learning curve. Superb kit, superb support, what more can I say.

    Rop Honnor

  • I have been using my 4224 PicoScope for years. I travel abroad so this has been ideal due to its physical size. Storage of waveforms on my Laptop is very easy allowing me to quickly email waveforms to my Colleagues.

    Andrew

  • Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope.

    Raul Trifan

  • We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations.

    J Mohanty

  • PicoLog TC-08: This is a very nice unit that works consistently and reliably.

    Jeff Hulett

  • It is a great scope. I had a weird problem - it did not work on one of my PC’s. Customer service gave me first class service. If I could give 6 stars for customer service - I would do so.

    Niels Larsen

  • Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. Since the included software is really stable, this type of device is a great tool for great tasks!

    Helmut Schoettner

  • A superb piece of equipment worth its weight in gold

    Nigel Clinch

  • So simple to use & beats any other I have ever used hands down.

    John D Samsing

  • Rather than webcam our benchtop scope screen, it was suggested we use a PicoScope to share waveforms via screen share.

    We were a bit hesitant at first … but it worked flawlessly, and everybody is now out shopping for PicoScopes!

    T Lövskog • SVP of Innovation at Additude AB

  • Great functionality in a compact size. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. Calibration equipment is a breeze with that feature.
