•Software Compatibility: The 4x25A is fully compatible with PicoScope 7 Automotive, a
powerful software packed with guided tests and a waveform library. The 2000 series is not
compatible with the automotive software. No guided tests or waveform library. No access the Pico Diagnostics Tests software. (Battery/Start/Charging, Relative Compression, Power Balance, or NVH)
•Robustness and Overvoltage Protection: The 4x25A is housed in a rugged case
designed to withstand the tough environment of a repair shop. The 4x25 can handle a channel input voltage of ±200V, providing significant protection against accidental overvoltage. The 2000 series is less durable and has a fragile ±20V input limit, making it easy to damage with common automotive signals like injector voltages. You'll need attenuators much more often with a 2000 series.
•Safety and Grounding: 4x25A's have floating ground inputs. This design isolates each channel, preventing short circuits and allowing for safe, accurate measurements across components that are not referenced to the chassis ground (Think inductive crank sensors and hall effect cam sensors at the same time). The 2000 series uses a common ground, which can make it possible to create ground loops that damage the scope internally or circuits in the vehicle.
•Performance Specifications: The 4x25A vastly outperforms the 2000 series in every key area for diagnostics:
• Memory: With 250 million samples, the 4x25A can capture long, complex data streams (like a full CAN bus recording) in high detail. The 2000 series' tiny 8 thousand sample memory will limit how you capture information by either trading low sample rate for longer captures or fast sample rate and only being able to see the data captured on the screen.
• Resolution (Bit Rate): The 12-bit resolution (number of vertical measurement points) of the 4x25A provides a much more precise and detailed waveform. The 8-bit resolution of the 2000 series can easily miss these critical details. 12 bit = 4096 vertical levels, 8-bit is only 256 vertical levels.
• Sample Rate: The 400 MS/s sample rate of the 4x25A is crucial for accurately capturing fast signals from modern vehicle networks like FlexRay, whereas the 100 MS/s on the 2000 series is insufficient.
In short, while the 2000 series may be a budget-friendly scope for basic electronics, it falls short in many ways for professional automotive diagnostics.
