Abstract

We introduce a fast pulse sampling module with the use of switched-capacitor arrays (SCAs). The module is in the size of 3U for PCI extensions for Instrumentations (PXI), and there are a total of six channels with a sampling rate of up to 5 giga samples per second (GS/s) per channel. With this module, we evaluate the issues of fast pulse timing from reconstructed waveform, as well as the scheme of interleaved sampling between adjacent channels within the module. The timing precision of this module is proved to be below 10 ps RMS at 4.7 GS/s after a series of calibration strategies. We have also achieved 9.4 GS/s with two channels interleaved on board.
