PicoScope 4227 Set, High Resolution DSO for the USB Port, 2-Channel, 12 Bit, 50MHz, 250 MS/s
Do you desire an oscilloscope that has both precision and speed? The 2-channel PicoScope 4226 and 4227 are precision USB oscilloscopes that are suitable for general, scientific and field-service use. With 12-bit resolution (adjustable up to 16 bits in enhanced resolution mode) and 1% accuracy they also make an excellent choice for noise, vibration and mechanical analysis.
The convenience and speed you need
Your PicoScope 4227 is powered from the USB 2.0 interface, so there’s no need for you to carry an external power supply or batteries with you. The USB port also delivers high-speed data to your PC to give you a responsive, high-resolution display. With up to 250 MS/s real-time sampling, the PicoScope 4227 is the fastest USB-powered 12-bit scope available.
- Up to 250 MS/s real-time sample rate
- Up to 100 MHz bandwidth
- 32 M sample buffer memory
- 2 channels
- Free software updates
- 5 year warranty

Deep memory that doesn’t compromise performance
Thanks to the advanced 32 megasample buffer which is ‘always on’, there is never a compromise between buffer size and performance. Your PicoScope always maximises both the buffer size and display update rate at the same time. Now you can easily capture every detail of every waveform without compromising the performance of your oscilloscope.
Your complete software package
The PicoScope 4226 and 4227 are supplied with PicoScope oscilloscope software. PicoScope is your complete test and measurement lab in one easy-to-use application. As well as a fully-functioning oscilloscope with advanced features such as digital persistence, math functions and automated measurements, PicoScope software also allows you to use your PicoScope 4226 or 4227 as a spectrum analyzer, function generator and arbitrary waveform generator. PicoScope is free to use on as many PCs as you like, it’s regularly updated with new features and enhancements, and you can always download the latest version — for free — from our website.
(We know that you may want to write your own software or use a third party application to control your PicoScope oscilloscope. No problem. We also provide a free software development kit that contains various software drivers and example code.)
A pedigree you can depend upon
The PicoScope 4226 and 4227 are our 6th generation of 12-bit PC oscilloscopes. With almost 20 years’ experience in PC-based test equipment design we know that our users demand — and deserve — quality, performance and affordability. We don’t like to disappoint.
The speed, precision and versatility you need
With up to 100 MHz bandwidth, 250 MS/s real-time sampling, 12-16 bits resolution and 1% accuracy the PicoScope 4226 and 4227 are powerful and fast oscilloscopes. But your PicoScope is much more than an oscilloscope: with an integrated spectrum analyzer, function generator and arbitrary waveform generator your PicoScope is a complete test and measurement laboratory that is small enough to take anywhere.
When speed, precision and versatility are important, a PicoScope 4226 or 4227 is what you need.
