More Info

Now you can see a twelve-cylinder secondary ignition parade on your Pico Scope. Mixmaster can produce a parade display of up to twelve cylinders using a single channel of your Pico Scope. If you have a two-channel or four-channel Pico Scope the Mixmaster will also display two engine banks separately with up to six cylinders per bank.

Pico Mixmaster is battery-powered, rugged and conveniently portable. It is supplied with a set of four secondary ignition leads, three BNC leads to connect to the oscilloscope, and an engine-block ground lead. It has a trigger output to help synchronise the scope to a known cylinder, and a switch to deal with negative-going wasted-spark signals. There's no software to install, and it works with PicoScope or any other automotive oscilloscope program.
