PicoScope 4224 & 4424
High-Resolution USB Oscilloscopes
Now you can measure everything from small signals from sensors to high voltages from power supply circuits & motor drives.
The 2 channel PicoScope 4224 and the 4 channel PicoScope 4424 are high resolution 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.
  • Up to 80 MS/s real time sample rate
  • Up to 20MHz bandwidth
  • 32M sample buffer memory
  • Up to 4 channels
  • Free software updates

Your Complete Software Package

The PicoScope 4224 and 4424 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 allows you to use your PicoScope 4224 or 4424 as a spectrum analyser. 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 from the Pico 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.

The Convenience and Speed You Need

Your PicoScope 4000 Series scope 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 80 MS/s real time sampling, the 4000 Series are one of the fastest USB powered 12 bit scopes available.

Deep Memory Without Compromising Performance

Thanks to the advanced 32 megasample buffer which is ‘always on', there is never a compromise between buffer size and performance. The PicoScope 4000 Series 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 scope.

An IEPE Oscilloscope That You Can Afford

Normally if you want to use IEPE sensors you either need to buy an expensive oscilloscope with an IEPE interface, or an equally expensive add on module. Not anymore. Our PicoScope 4224 IEPE is at a price you can afford, and features an integrated IEPE interface making it compatible with industry standard IEPE accelerometers and microphones.

Your Powerful High Resolution Oscilloscope

With both 2 and 4 channel versions, 20MHz analogue bandwidth, 80MS/s real time sampling, 12~16 bits resolution, 1% accuracy and a wide input range, a PicoScope 4000 Series USB scope is the powerful high resolution oscilloscope that will fulfill your needs.

PicoScope Oscilloscope Software

PicoScope Oscilloscope Software

PicoScope is your complete test and measurement lab in one easy to use application

Start PicoScope, click Auto setup and your PC is transformed into a powerful oscilloscope with the timebase and triggering already set up. Click Persistence mode and you can emulate the phosphor display of a conventional analog scope, useful for displaying complex analog signals and spotting glitches. Click Spectrum mode and your PC becomes an FFT spectrum Analyser. And there's more….

Using the automated measurements feature in PicoScope you can automatically measure everything from peak to peak voltage, to rise time and signal to noise ratio, turning your PicoScope 4000 Series into a multimeter. “But my multimeter can measure resistance!” So can your PicoScope! Measure the voltage using one channel of your scope, the current using another channel then use the built in math functions to automatically display the resistance.

Despite the many advanced features and functions, PicoScope is still fast and easy to use. Even if you've used a traditional “knobs and buttons” oscilloscope for many years, the intuitive controls and familiar Windows user interface of PicoScope make it incredibly easy to use.

PicoScope software is regularly updated with feature extensions and improvements. These can be downloaded for free from our website and ensure that your oscilloscope will always have the latest features and enhancements.
