terval must be set between 0 (default) and 65ms. Aperture must be set between
60ms and 2.5us. The value of iPostSamples must be set between 1 and the buffer size.
The buffer size is 80 for Apertures of 160ms to 1.4ms, and 120 for Apertures in the range

DMMReady returns TRUE, it should not be called again since it prepares the buffer for
