PicoScope 4823, 8-Channel Automotive Diagnostics Oscilloscope, without Accessories
PicoScope 4823 is the world's first high-resolution 8-channel automotive oscilloscope, fast enough for CAN, CAN FD and FlexRay, including serial data decoding. It is preconfigured for all Pico automotive measuring and probing devices and provides access to more than 150 guided tests, as well as thousands of wafeforms from the Pico Waveform Library, which now supports 8 channels.
It has 8 channels, which in contrast to the 4-channel automotive oscilloscopes have a common grounding. The maximum input voltage is now 50V and has protection up to max. 100V. The sampling rate with 80MS/s is lower than with the previous 4-channel automotive oscilloscopes (10MS/s with all 8 channels used).
The other technical data are in line with the expectation of a deep memory PicoScope with 10-bit resolution, 20MHz bandwidth, 256MB buffer memory and SuperSpeed USB 3.0 interface.
While Pico's 4-channel automotive diagnostic oscilloscopes are the best solution for standard automotive diagnostic applications, there are needs for 6 or more channels in aftermarket and vehicle maintenance, such as:
- V6/V8 timing (4/6 cam + crankshaft, + WPS measuring) and VVT timing.
- Trucks, construction and agricultural machinery that require technicians to mash electrical and hydraulic measurements on multiple valves simultaneously to diagnose problems with system interaction.
- Complete system diagnostics on components (including plus, ground, signals and amperage)
- General engine diagnostics.
The use of the PicoScope 4823 should only be considered if there is an actual need for 8 channels that excludes the use of the proven 4-channel PicoScope 4425.
The PicoScope 4823 is available individually as well as a set with comprehensive, practical measuring accessories.
PicoScope is used by authorized and independent garages more than any other measuring system, because it gives them the confidence, support and solution to quickly find and document most vehicle failures. Those who purchase a PicoScope benefit from more than 25years of experience with diagnostic oscilloscopes from Pico Technology.
