Picoscope 4 Channel Standard Diagnostic Kit 4425A (PQ178)

● In Stock


The PicoScope 4425A Standard Diagnostic Kit expands on the Starter Kit to provide a more comprehensive oscilloscope diagnostic solution for automotive technicians. Featuring the advanced 4425A 4-channel oscilloscope with smart PicoBNC+™ connectivity, this kit delivers quicker setup, automatic probe recognition, and enhanced diagnostic capability across a broader range of automotive systems.

This kit includes a more extensive probe and accessory set than the Starter Kit, enabling faster access to key test points and improved signal capture quality across common electrical, sensor, and actuator circuits. Automatic probe detection and guidance help reduce setup errors, while deep memory and high-resolution sampling allow detailed waveform capture and analysis.

Compatible with a full suite of automotive diagnostic software, including PicoScope 6, PicoDiagnostics, and PicoScope 7 Automotive (currently in beta for the 4425A), the Standard Diagnostic Kit provides access to a wide range of guided test procedures, waveform libraries, and structured diagnostic workflows. These tools are designed to assist technicians in capturing, interpreting, and comparing live waveform data to known-good patterns for more accurate fault confirmation.

The kit supports both existing BNC accessories and smart probe interfaces, enabling seamless integration with a range of probes, transducers, and optional accessories, making it suitable for workshops looking to elevate their diagnostic capability without investing in multiple individual tools.
