PicoScope 4823 8-channel Automotive Oscilloscope

California Residents: Proposition 65 Warning
Eligible for FREE Ground Shipping(Eligible for FREE Ground Shipping)

The 4823 is a high-resolution, 8-channel automotive oscilloscope that features a common-ground configuration, a maximum input range of 50V (protected to 100V), and a maximum sample rate of 80MS/s (10MS/s if using all 8 channels).

The 4823 is the same 8-channel automotive scope module included with the Pico PQ184 Professional Diagnostic Kit.

The scope includes protection fuses on the eight inputs and is compatible with the PicoScope Automotive software.
- fast enough for CAN, CAN FD, and FlexRay including serial data decoding
- pre-configured for automotive probes
- compatible with Pico Automotive software which includes more than 150 Guided tests
- provides access to the Pico waveform library which now supports 8 channels
- 12-bit resolution
- 20 MHz bandwidth
- 256 MS buffer memory
- SuperSpeed USB 3.0 interface

Comparison 4823 vs 4425
- 50V vs 200V inputs 
- 80MS/s vs 400MS/s
- Common ground vs Floating inputs
- No ConnectDetect™ vs ConnectDetect™
- No hardware filter available vs Hardware filter available
- No bracket vs Integral hanging bracket
- End caps vs Protective rubber boot

Why use an 8-channel scope?
- V6/V8 Cam timing (4/6 cams plus crank, and sometimes a WPS), and VVT timing systems.
- Trucks, construction and agriculture equipment where technicians require a mix of electrical and hydraulic measurements on multiple valves simultaneously to diagnose problems with system
- Full system diagnosis on components (including power, ground, signals, current)
- General engine diagnostics

Tight spacing!


The 4823 scope module is the same height and width as the 4425 but the 4823 has twice as many channel inputs. That means it will be more difficult to add and remove the leads. The protective boot adds to the crowding.


There is 10.22 mm between each BNC input on the 8-channel 4823. That is tighter than the older 4423/3423 modules.
