4425 4-Channel Automotive Oscilloscope from Pico

Your 4425 4-Channel Automotive Oscilloscope from Pico turns your laptop or desktop PC into a powerful diagnostic tool. Think of it as the X-ray machine of diagnostics, letting you see the changing signals inside wires.

Also consider our less-expensive 4225 2-Channel Automotive Oscilloscope.

PicoScope Electrical System Tests

Visit our new Test Library Page!

A PicoScope is the heart of a range of automotive diagnostic systems. You can test virtually all electrical and electronic components and circuits in any vehicle, including:

  • Ignition Systems (Primary and Secondary, COP and Wasted Spark)
  • Injectors and Fuel Pumps
  • Batteries and Starter Motors
  • Alternators and Charging Regulators
  • Lambda, Airflow, MAP and ABS Sensors
  • Knock Sensors
  • Diesel Glow Plugs
  • Exhaust Gas Recirculation Actuator
  • Electronic Throttle Control and Servo
  • CAN, CAN-FD, LIN and FlexRay
  • Keyless Entry and Parking Sensors
  • Road Speed Sensor
  • Coolant Temperature Sensor

PicoScope Mechanical System Tests

Your PicoScope can also test mechanical systems such as:

  • Relative Compression
  • Distributor
  • CAM, Crank, Injection, Ignition Timing
  • Relative Power contribution from each cylinder
  • Misfire Detection
  • Variable Valve Timing

PicoScope Pressure Sensor Tests

When combined with a WPS500X pressure sensor, your PicoScope can also test:

  • Manifold Pressure, Cranking, Running and Snap Throttle
  • Absolute Compression across all cyclinders
  • In cylinder Compression Cranking and Idling (Full graph of the cycle not just the peak pressure)
  • Common Rail Diesel Injectors - Back Leakage Testing
  • Fuel Pressure and Fuel Pump Pulsations
  • Exhaust Gas Pulsations (Relative Cylinder Contribution)
  • The WPS600C Pressure Sensor, rated at 600 bar extends your tests to Hydraulics Systems

Noise Vibration and Harshness (NVH) Tests

Your 4425 4-Channel Automotive Oscilloscope can also be used for comprehensive Noise, Vibration and Harshness (NVH) testing and analysis. Just add one of our PicoScope NVH Kits.

In order to use your 4-Channel Automotive Oscilloscope, you will need a PC and some test leads to connect to the vehicle. Most people purchase one of our award winning Automotive Diagnostics Kits. These money-saving kits contain everything you need. Please consider our 4 Channel Starter or Diagnostic Kits or our more advanced kits (listed above) rather than purchasing the oscilloscope on its own.
