The next generation of scopes

Diagnostics from Pico

Published:  03 December, 2014

The PicoScope 4225 and 4425 are the new 2 and 4 channel automotive scopes which replace the long-serving PicoScope 4223 and 4423 and which provide a number of new features and upgraded performance for the same price as the older scopes. New features provide technicians with additional measurement capabilities and techniques. These capabilities allow the capture of more information and finer detail, over extended periods of time. 'ConnectDetect' is a new feature that confirms on-screen and on-device, that your probe has made connection to the circuit, ideal for hidden connectors. Read more about this in our TestBench on page 35. The BNC input channels are isolated from each other and from USB ground, allowing the technician to directly measure across components, carry out voltage drop tests, test reverse polarity motors and measure floating ground sensors using all inputs at the same time. The input range has been increased to ±200V, reducing the need for attenuation when testing injector circuits, for example. The new scopes can capture up to 400 million samples per second and can measure high speed CAN and FlexRay signals. The new generation scopes have eight times the memory of their predecessors. More samples can be taken and finer detail is revealed when zooming, with the additional benefit of more waveform buffers to review when looking for elusive, intermittent faults.
