Automotive Spark Immunity Simulator

TBZ-50

The TBZ-50 automotive spark immunity simulator is designed for testing vehicle electronic equipment such as taximeter and vehicle traveling data recorder. Frequency signal is controlled by single chip to output to ignition module. Ignition coil is controlled by ignition module to produce HV pulse and form reliable spark with adjustable frequency and spark gap.

Frequency value of spark is displayed on nixie tube. With the frequency scanning function, spark in the process of vehicle idling, accelerating and decelerating can be simulated.
