PicoScope 8-Channel 4825B Automotive Oscilloscope
The PicoScope 4825B is an 8-channel automotive oscilloscope built to test more so you can test faster. Streamline your diagnostics by capturing complex electrical, network and sensor signals in real time.
- Capture quad cams, crank, ignition and injectors in a single pass.
- Combine multi-circuit current monitoring with multi-network data decoding to identify intermittent control module wake-up issues.
- Measures 3-phase motor voltage, current and rotor signals simultaneously.
- Capture up to eight accelerometers or microphones to pinpoint elusive drivetrain and chassis noises.
Changes vs 4823
The 4825B is more closely related to the 4425A product than the previous 4823 and shares
the same floating ground PicoBNC+ input structure. Due to the requirements of EN61010,
we are limited to a 100V maximum input range on the 8-channel scope rather than the 200V
of 4425A.
Higher Bandwidth
Increased from 20MHz to 40MHz, offering improved fidelity of high-speed signals such as
10Base-T1S and CAN XL.
Higher Sampling Rate
Increased from 80 million samples/second to 160M samples/second for modern vehicles,
including high-speed FlexRay and CAN-FD networks.
Deeper Memory
500 million sample memory for capturing intermittent faults and longer logging.
Faster Data Transfer
Completely USB Type-C® connected and powered for high performance and portability.
Smart Probe Interfacing
Automatic software configuration—no more incorrect settings!
Powered Probes
Always on, no batteries needed, and ready for immediate use.
Channel Status Lights
Clear indicators for probe connection and status.
Backward and Forward Compatibility
Works with all existing BNC and PicoBNC+ probes.
Hardware Filter
Like the 4425A, the 4825B features a switchable low-pass hardware filter to remove
unwanted and distracting noise for applications such as current measurement.
