4823 8-Channel Automotive Oscilloscope and Professional Automotive Kit
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.
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.
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.
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 on our oscilloscopes page (click on the Specifications tab) for full details. We have summarised notable differences below:
| Pico 4225 | Pico 4425 | Pico 4823 | |
|---|---|---|---|
| Channels | 2 | 4 | 8 |
| Arbitrary Waveform & Function Generator | No | Yes | |
| Floating Grounds | Yes | No | |
| Input Range | 200V | 50V | |
| Input Protection | 250V | 100V | |
| Buffer | 200MS | 256MS | |
| Maximum Sample Rate | 400MS/s | 80MS/s | |

Why are 8 channels necessary?
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.
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.
Launch
The 4823 8-Channel PicoScope (PICO-PQ185) and the 8-Channel Professional Kit (PICO-PQ184) are brand new products and will only be shipped from the UK from the 15th July 2019. Pricing will be provided on request. We believe that there will be considerable world-wide demand for these products. If you wish to acquire one of these products, please place your order soon so that one can be reserved for you.
