PicoScope: Power, portability and versatility
Pico Technology continues to push the limits of USB-powered oscilloscopes. The new PicoScope 3000 Series offers the highest performance available from any USB-powered oscilloscope on the market today. The PicoScope 3000 Series has the power to perform in many applications, such as design, research, test, education, service and repair. Pico USB-powered oscilloscopes are also small, light and portable. They easily slip into a laptop bag making them ideal for the engineer on the move. There is no need for an external power supply, making them ideal for field use.
High bandwidth, high sampling rate
Most USB-powered oscilloscopes have real-time sampling rates of only 100 or 200 MS/s. The PicoScope 3000 Series offers a market-leading 500 MS/s. ETS mode boosts the maximum effective sampling rate further to 10 GS/s, allowing more detailed display of repetitive signals.
Huge buffer memory
The PicoScope 3000 Series offers memory depths up to 128 million samples, more than any other oscilloscope in this price range. Other oscilloscopes have high maximum sampling rates, but without deep memory they cannot sustain these rates on long timebases. The PicoScope 3206B can sample at 500 MS/s at timebases all the way down to 20 ms/div.
