微波动感电感探测器在天文观测中具有多种潜在应用。我们构建了一个结合专用模拟板和市售数字板的动感电感探测器数据采集系统，以满足天文测量的要求，例如宇宙微波背景的观测。本文报告了数据采集系统的发展现状。我们已经使用直接下变频方法对信号进行解码，实现了 120 个通道的同时读出。使用系统和实际探测器的功能开发和测试了各种软件。
Microwave kinetic inductance detectors have a variety of potential applications in astronomical observations. We built a data acquisition system for kinetic inductance detectors combining a dedicated analog board and a commercially available digital board to meet the requirements of astronomical measurements, such as observation of the cosmic microwave background. This paper reports the status of the development of the data acquisition system. We have already achieved simultaneous readout through 120 channels using a direct down-conversion method to decode the signal. A variety of software has been developed and tested using the functionalities of the system and actual detectors.
