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

acam TDC-GPX Time to Digital Converter

The TDC-GPX multifunctional architecture makes it a very powerful time-to-digital Converter (TDC). The TDC-GPX is designed for applications where high single-shot resolution, best pulse-pair resolution, and high measurement rates are required. This is a huge step forward in time measurement based on TDCs.

The TDC-GPX features 4 different operation modes, 8-channels with 32-fold multi-hit capability and a resolution down to 10 ps. These features make the TDC-GPX perfectly suited for industrial and scientific applications.
