Please note, you will be supplied either with a TA400 or TA499 probe. These probes have a fixed x10 attenuation and are intended for high-speed signals like CAN, FlexRay and also for higher voltage signals such as primary ignition. The TA499 has a fixed 4mm tip, where the TA400 has a detachable adaptor tip (TA411), allowing the probe to be used with any of the 4mm clips. The TA400 and TA499 are both automatically recognised by PicoScope software when they is connected to the scope. These accessories are only available for PicoBNC+ and will not work with older PicoScope models.
