Knock Calibrator
The μDCAT Knock Calibrator is a version of μDCAT that contains asynchronous
sampling and knock calibration XControl. The Knock Calibrator requires a cDAQ-9174 or a
cDAQ-9178. The cDAQ chassis support multiple analog input time bases. The knock calibrator
also requires different activation than the standard μDCAT version.
The Asynchronous Measurement setup is similar to the Synchronous Measurement
setup as shown in Figure 22. The MeasurementType of the knock sensor should be set to
Acoustic. If no acoustic sensor is found, the cylinder pressure trace will be used. At least one
synchronous measurement must be used. However, asynchronous measurements are optional.

The encoder setup has been moved to the Engine Setup tab as shown in Figure 23. The
inputs setup is the same as the standard μDCAT version.
