PicoScope 4425A 4-Channel Automotive Scope (PQ174)

The PicoScope 4425A Automotive Diagnostic Oscilloscope is a 4-channel vehicle diagnostic device for testing automobile engines. This latest PicoScope design combines all the strengths of the existing 4425 automotive scope but adds smart interfaces for powered and intelligent accessories.  This new accessory interface, called PicoBNC+™, combines the standard BNC connector with active digital and power connections. The 4425A will also work with existing BNC probes and accessories, preserving previous investments.

The 4425A model makes it even easier and more intuitive for inexperienced users and experts alike, with new test capabilities and future-proofing as part of the design. 

The PicoScope 4425A with PicoBNC+ connectors makes it simpler than ever for new users to become efficient and productive with PicoScope, while saving valuable time for more experienced users. It is available in a variety of kit configurations that include a wide assortment of test probes to take advantage of the new PicoBNC+connector.

The PicoBNC+ provides a physical and digital connection between the 4425A scope and a test probe equipped with the PicoBNC+ mate.

• Push it on, pinch and pull it off; does not require a twist like the old-fashioned BNC connectors. 
• It provides power from the scope to the probe, great for overnight battery drain tests! 
• It allows the probe to identify itself to PicoScope software which will auto-configure for that specific probe.
• It will auto-zero a current clamp. 

The PicoBNC+ is backwards compatible with your existing Pico or third-party probes equiped with a traditional BNC connector which only provides a physical connection to the scope. This new PicoBNC+ connection is a plug-and-play push to connect design. Interactive LEDs on the scope match the color-coding on the probes when connected. Probes are automatically recognized by the PicoSoft software and settings are adjusted accordingly, making diagnostics even faster and easier with the PicoScope 4425A automotive oscilloscopes. PicoBNC+ probe recognition saves time, reduces errors, and allows new users to become confident and comfortable faster than with other scopes.  PicoBNC+ powered probes mean that current clamps are always ready for action, with no batteries or limit on long-term measurements.  PicoBNC+ software control provides Auto-zero for probes, it avoids manual switch settings and simplifies probe setup for users. 

The front panel of the PicoScope 4425A with PicoBNC+ includes bright status lights for each channel. After loading a data file or selecting a guided test, PicoScope 7 software will show you which probe to use and the status lights will indicate which channel to connect it to. If you connect the wrong probe the software will alert you.

Using a PicoScope has never been faster, easier or more reliable.

The PicoScope 4425A scope module includes the hardware features that made PicoScope 4425 the most powerful and versatile automotive scope.

• 400 M samples/second and 20 MHz bandwidth to make sure you can test the latest vehicles such as those with high-speed FlexRay or CAN-FD networks
• 12-bit (16-bit enhanced) resolution your waveforms in high definition
• 250 M sample memory buffer for long-duration captures; ideal when you are trying to diagnose intermittent faults
• USB 3.0 data transfer speeds and power, providing you with high performance and portability
• Floating inputs for non-grounded measurements and voltage drop tests
• 200 V input range
• ConnectDetect to ensure you have a good connection
• Hardware filters and frequency measurement
• Advanced digital triggers. Unique among automotive oscilloscopes, these trigger modes allow you to trigger when there is too long a time gap (such as when an injector fails to fire). They can also trigger and sound an alarm when a sensor signal goes out of range.
• Filters. Some signals are noisy, as wires in the loom pick up noise from other sources. The vehicle ECUs filter this noise out. The PicoScope 4425A has selectable hardware filters to remove this noise, so you see what the ECU sees.
• Hardware frequency measurement. Flow sensors and some airflow sensors output a digital frequency signal. Most oscilloscopes cannot extract usable diagnostic information from this, but your PicoScope can convert it to a conventional analog waveform (as shown in this MAF sensor example).
• Compatible with Pico transducers (WPS500X and WPS600C) and third-party transducers such as the Firstlook.
• Compatible with Pico NVH interfaces.
