---With the Mixmaster 12-channel automotive signal mixer you can view an ignition parade display of up to 12 cylinders on any lab scope. ---Mixmaster can produce a parade display of up to 12 cylinders using a single channel of your lab scope. If you have a two-channel scope, then Mixmaster can also display 2 engine banks separately with up to 6 cylinders per bank. ---Mixmaster includes a trigger output, derived from one of the 12 input signals, which can be used to synchronize the scope to a known cylinder. Additionally, Mixmaster features a simple switch so you can invert a bank of signals to deal with negative-going signals on wasted-spark systems. ---Designed for use with the Automotive Oscilloscope Kit, Mixmaster can also be used on virtually any other lab scope, and can be used on both DIS and distributor ignition systems.
