Oscilloscopes for production testing, analysis, design and debugging

Paul Boughton
The new PicoScope 4226 and 4227 represent the sixth generation of high-resolution oscilloscopes from Pico Technology.

Powered from the USB port and including a built-in arbitrary waveform generator, these scopes contain everything you need to make accurate high-speed measurements. Just plug one into a laptop or desktop computer, run the software supplied, and get to work.

The latest PicoScope 4000 Series oscilloscopes have two 12-bit input channels with a bandwidth of 50 MHz or 100 MHz, allowing them to capture detailed waveforms for production testing, scientific analysis, and electronic design and debugging. The third input is a dedicated external trigger. The fourth connector is the output of the signal generator, which allows you to load an arbitrary test signal, draw your own waveform using the graphical editor, or use one of the six preset waveforms.

The PicoScope 4227 can sample at rates up to 250 MS/s, and the PicoScope 4226 up to 125 MS/s. Both models have a deep 32‑megasample buffer memory that enables the maximum sampling rate to be used even on slow timebases. The buffer can hold up to 10,000 waveforms, which are displayed in a pop-up navigator window for easy access.

A fully enabled version of the PicoScope oscilloscope software is included in the price. PicoScope for Windows offers a wide range of advanced functions such as mask limit testing, alarms, serial data decoding, programmable low-pass filtering, math channels, reference waveforms, Digital Color and Analog Persistence display modes and XY mode. The advanced trigger types include pulse width, window, interval, dropout, and runt pulse.
