PP799 (PS 4262) - 

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.
Now you can measure everything from small signals to large voltages
The PicoScope 4000 Series have input ranges from ±50 mV to ±100 V full-scale (±50 mV to ±20 V for the PicoScope 4224 IEPE) so you can measure small signals from sensors as well as higher voltages from power supply circuits and motor drives.
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.
