Tone Burst Measurement (TBM)

The TBM Module provides an automatic tone burst measurement sequence based on Standard ANSI/CEA-2010.
Using a fully adjustable tone burst stimulus, the maximum sound pressure level is measured. For a user defined set of frequencies, the measurement is automatically repeated with increased input level. If the distortion in the sound pressure has reached a user defined threshold, the measurement is stopped and the peak SPL is reported.
Optionally, a second state signal (displacement, current or voltage) is measured simultaneously.

Variable burst cycles
Flexible filtering for peak measurement
Monitor 2nd state signal (displacement, current, voltage)


The Burst measurement module is designed to run band limited burst measurements versus input voltage and frequency. The results are evaluated in the frequency domain towards a threshold curve.
For each frequency, the voltage is increased until the threshold curve is reached. The highest voltage not below the threshold curve is used to calculate the peak level of this state signal (according to CEA2010).
