Product Overview

High Speed ADCs

Our analog-to-digital converter boards are optimized for the analysis of analog pulses at very high repetition rates as occurring in TOF-MS, TCSPC, FLIM and LIDAR instruments. Unlike other digitizer boards, they detect pulses on the fly and stream the pulse shape data directly to main memory, minimizing bandwidth requirements, latency and CPU load. Two examples from our portfolio are shown below.

Time Measurement

Our time-to-digital converters target high-speed pulse processing applications that do not require information on analog pulse shapes. Several examples from our portfolio are shown below.
