Free downloadable firmware trial version
Free downloadable DPP-PHA Trial version for 724, 725, 730, 2740, 2745 and 2730 series.
The user can download and install DPP-PHA firmware without any license key and use it with time frame limitation: every 30 min the user have to restart (Power off/power on) the board
To get time-unlimited operating DPP-PHA the user should purchase a License
780/781/V1782 Digital MCA are factory provided with time-unlimited operating DPP-PHA firmware and don’t require licensing
DPP-PHA (Digital Pulse Processing for Pulse Height Analysis) firmware is fully controlled by CoMPASS, the CAEN multiparametric spectroscopy software for Physics application.
A digitizer running DPP-PHA firmware becomes a multichannel data acquisition system for nuclear physics or other applications requiring radiation detectors. The digitizers accept signals directly from Charge Sensitive Preamplifiers or photomultipliers and implement a digital replacement of Shaping Amplifier and Peak Sensing ADC, allowing the user to perform energy and time measurements. All these functions are performed inside the FPGA without any use of external cables, nor additional boards or delay lines. Therefore, a single compact system takes care of the acquisition, replacing the traditional analog boards.
It is also possible to realize multi-board systems and, eventually, perform coincidences among channels thanks to the DPP-PHA firmware features: the front panel clock, the trigger and the general-purpose LVDS I/Os connectors (VME only) make it possible to synchronize multiple boards.
