TIME TO DIGITAL CONVERTERS

TDC-GPX Multifunctional High-end Time-to-Digital Converter.

Our flagship component for high-end applications including automated test equipment, mass spectroscopy, laser rangefinders, and medical PET scanners is the TDC-GPX.

The architecture of the GPX is optimized for maximum measurement speeds, optimal pulse-pair resolution, and greatest single-shot resolution. Its four operating modes, eight channels (with a 32-fold multi-hit capacity), and a resolution down to 10 ps (rms) make it perfect for industrial, medical, and scientific applications in which highest performance and precision are required.
