To get time-unlimited operating DPP-ZLEplus the user should purchase a License.
The Zero Length Encoding (DPP-ZLEplus) firmware has been developed for the 2740, 2745 Digitizer 2.0 and 725, 730, 751 Digitizer 1.0 families. It allows the user to transfer the digitized waveforms in compressed mode, performing an enhanced Zero Suppression algorithm on the input signals.
DPP-ZLE continuously calculates the baseline of the input signals and, whenever a global trigger occurs (external trigger in case of 751 series), it searches for the significant input pulses within an user-defined Acquisition window. An input pulse is considered significant if it either exceeds an Upper Threshold or falls below a Lower Threshold referred either to the calculated baseline or absolute values in case of 751 series, or if it exceeds a single ZLE Threshold in case of 725, 730, 2740 and 2745 series.
It is possible to store not only the over threshold part of the significant pulses, but also the samples before and after the threshold crossing points by means of programmable Look Back and Look Forward windows.
A demo software (DPP-ZLEplus Demo Software) is available with C source files and Visual Studio project for a first approach to the DPP-ZLEplus algorithm principles and for a further personalization. The DPP-ZLEplus Demo software can also control and acquire data from multiple synchronized boards.
