获得的测试结果表明，基于DRS的BPM电子学提供了足够的分辨率，例如对于公共传输线BPM。其他系统特性，如线性度和温度漂移，以及它们的现场测量和基于FPGA的定期自校准的选项，目前正在研究中。下一个芯片版本“DRS4”预计将在PSI上上市，数量为10k，直到2008年秋季，具有更高的带宽、片上锁相环、更小的芯片尺寸和更好的接地，以及更小的采样单元的交流带宽变化。通过使用高级幅度拟合摘要，通过使用DRS4，可以进一步提高分辨率，例如用于带状线BPM
The obtained test results indicate that DRS-based BPM electronics provide sufficient resolution e.g. for common transfer line BPMs. Other system characteristics like linearity and temperature drift as well as options for their in-situ measurement and FPGA-based periodic self-calibration are presently being investigated. The next chip version “DRS4” is expected to be available at PSI in a 10k quantity until fall 2008, with higher bandwidth, on-chip PLL, smaller chip size with improved grounding, and smaller AC bandwidth variations of the sampling cells. Further resolution improvements e.g. for stripline BPMs are possible by using the DRS4, by advanced amplitude fit ABSTRACT
