Pulses visualization and backup software developed for hybrid radiometers RHC25 and RHC30 runs all 32-bit Windows environments (95, 98, NT, 2000, XP, Vista) without special configuration. The transfer of pulses between the electronic box and the connected PC is done through the RS232 DB9 serial link, with or without USB converter. The software license is multi-users and provided on CD Rom, and the RS232-USB link cable is provided with it. This user-friendly software transforms the hybrid radiometer into a true laser pulse analyzer: Each digitalized pulse is visualized and characterized in terms of energy, peak power and width.
