TIME TO DIGITAL CONVERTERS

TDC-GPX Multifunctional High-end 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.

    GENERAL FEATURES

    • PC supported system; communication via PCI interface
    • External ATMD-MB motherboard with AM-GPX (8 channels 81 ps resolution, 2 channels with 40 ps, 27 ps, or 10 ps resolution)
    • No additional power supply for the external motherboard. The power supply is provided by the interconnecting cable
    • Comfortable Windows software
    • User specific software can be written in every programming language
    • 2 operating modes (for details see the datasheets)
    •    a: AT-Bus polling mode up to approx. 200k measurings per second (without graphical display)
    •    b: Burst mode, up to approx. 1 Mio. measurings per second (peak, without graphical display)
    • On board measurement cache as FIFO. It can store up to 32 K measurements on average (1 K default)
    • External board with metal housing

    It’s modular and all-around open architectural system enables the ATMD to serve as an evaluation-kit as well as a complete and efficient measurement instrument.
