Other spectrum stabilizers operate on the principle of setting ‘’windows’’ on both sides of a peak and monitoring the difference in count rate. These complex instruments are difficult to set up accurately.

The DSS-100 works on a different principle. It takes advantage of the FWHM calculation feature of the PCA software . You simply set regions of interest over the one or two peaks being used for reference and the software periodically calculates the FWHM channels. If a difference is found indicating the peak DSS-100 adjusts the gain and zero offset of the ADC section of the PCA card to compensate.

The DSS-100 works with most types of detectors including NaI(TI) and HpGe.

The software with pug-in card allows slections of the periodic sampling rate of the FWHM channels and the amount of correction applied to the ADC.

When used with existing PCA cards, a small modificication is required to the PCA to allow connection of the DSS-100.
