The PicoBNC+ Coil-On-Plug (COP) and Signal Probe (TA398) is an advanced diagnostic tool from Pico Technology, designed for fast, non-invasive testing of coil-on-plug ignition systems and spark plugs. With the advent of COP ignition systems, where the coils are mounted directly to the spark plugs and do away with traditional spark plug wires, this probe is essential for picking up secondary ignition waveforms.
 Key Features:
 Rapid misfire detection: The probe enables rapid detection of misfires by directly displaying secondary ignition patterns.
 Automatic configuration: Equipped with a PicoBNC+ interface, the probe is automatically recognized by compatible PicoScope models (such as the 4225A or 4425A), ensuring easy installation and use.
 Flexible Design: The probe's slim, flexible construction provides easy access to hard-to-reach components in the engine compartment.
 No batteries required: The probe operates without external power, which increases ease of use.
 Applications:
 Testing COP Ignition Systems: By simply holding the probe to the coil, technicians can measure the secondary ignition waveforms without the need for back-probing or the use of adapters.
 Investigation of injectors and inductive actuators: In addition to ignition systems, the probe can also be used to analyze signals from injectors and other inductive components.
 Compatibility:
 The TA398 is specifically designed for use with PicoScope models equipped with the PicoBNC+ interface, such as the 4225A and 4425A. It is important to note that this probe is not compatible with older PicoScope models without PicoBNC+.
