New PicoScope 4425A for active diagnostics
Our exciting new PicoBNC+® probe connectivity, unique to PicoScope 4225A and 4425A oscilloscopes, provides you with:
- Channel status lights to show you which probes and channels to connect and their status when you load a data file or guided test
- Smart probe interfacing so that all your probe configuration takes place in the software – no more incorrect probe switch positions!
- Powered probes that are always on and ready to go – no more flat batteries, current clamp zeroing, or auto-off!
- Future-proofing of your diagnostic capabilities as we develop new probe technologies.
- Full backwards-compatibility with BNCÂ for all your existing PicoScope or third-party probes

Scan tool or scope?
We are often asked “Should I buy a scan tool or a scope”. The short answer is that you need both. A scan tool can often point you in the right direction, perhaps indicating a misfire on a specific cylinder but too often the less experienced technician then ends replacing several parts before the problem is solved. Oscilloscopes should be used:
- To eliminate guesswork and test individual components before they are replaced. This avoids “parts darts” where more and more parts are replaced until the fault goes away.
- To find intermittent wiring and connector faults.
- When a vehicle has a problem but no code has been set or when multiple / misleading codes have been set
- As the best way to find charging and starting problems.
- To find problems with actuators such as motors and injectors that are not monitored by the ECU.
- To identify mechanical problems such as compression and slipped / incorrectly fitted timing belts.
For the technician oscilloscopes lead to faster, more efficient diagnostics and a better understanding of how vehicle systems work. For the workshop using a PicoScope encourages a “fix it right” culture by reducing the number of parts changed on guesswork. The net result is improved customer satisfaction, increased repeat business and increased profits.
