Arbitrary Waveform and Function Generator

A useful addition is an arbitrary waveform and function generator which allows you to simulate waveforms to test and stimulate actuators and mimic responses from sensors. Please note that you may need a special isolator, buffer amplifier or driver to use this feature successfully in the field due to the relatively high impedance and low over-voltage specification of the output. Please contact us should you require any assistance with this feature.

Things to consider when deciding between a 4425 and the 4823

The 4425 is much more rugged than the 4823. It has a convenient hanging strap and a rubber boot to protect it in the harsh automotive environment. Its inputs can withstand much higher voltages than the 4823 (250V vs 100V). It has floating grounds and has a much higher sampling rate (400MS/s vs 80MS/s). The 4823 has many specialised applications but the general workshop technician should, as a general rule, always choose the 4425 unless there is a really pressing need for an eight channel instrument.

Pico Automotive have introduced a new 8-channel Automotive Oscilloscope called the 4823. It is the world's first high-resolution, 8-channel automotive oscilloscope fast enough for CAN, CAN-FD and FlexRay, including serial data decoding.

Why are 8 channels necessary?
4823 8-Channel Automotive Oscilloscope Front Panel

Eight channels facilitates testing of five, six and eight cylinder engines. V6 / V8 CAM timing (4/6 cams plus crank, and sometimes a WPS pressure sensor), and VVT timing systems. Trucks, earthmoving and agricultural vehicles often require a mix of electrical and hydraulic measurements on multiple valves simultaneously to diagnose problems with system interaction. The 4823 is ideal for full system diagnosis on components (including power, ground, signals, current) and general engine diagnostics where many signals need to be monitored simultaneously.

The 4225 and 4425 vs the new 4823 PicoScope

The 4823 is very similar to the 4225 and 4425 oscilloscopes (i.e. 12 bits, 20 MHz) but there are a few specifications and features that are different. Please refer to the specifications for full details. We have summarised notable differences below:

4823 8-Channel Automotive Oscilloscope Specifications

The 4823 is similar to the 'Test and Measurement (electronics)' 4824, except that it has protection fuses on its inputs and can be used with the PicoScope Automotive software.
