Mixmaster 12-Channel Automotive Signal Mixer

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.

Mixmaster is battery powered and includes a low-battery indicator. The shockproof rubber case makes Mixmaster suitable for heavy-duty workshop use and incorporates a handy stand to make it easier to use.

Mixmaster is supplied with three BNC leads to connect to the oscilloscope, an engine-block ground lead, and a set of 4 short secondary ignition leads. Additional packs of secondary ignition leads can be purchased separately.

Mixmaster is a cost-effective way to display parade ignition waveforms on your lab scope. Compact and battery powered, it is ideal for mobile automotive diagnostics, and makes a valuable and inexpensive addition to your tool kit.
