研制了一种用于毫米波天文学的微波动力学电感探测器（MKID）阵列的数字频率复用电子学样机，该样机可实现真实的实时监测。它只需要2个同轴电缆的仪器大阵列。为此，产生频率的激励梳并通过检测器馈送。直接频率合成和数据采集在很大程度上依赖于一个大的FPGA使用并行和流水线处理。该原型可以在125 MHz的带宽上测量128个谐振器（像素）。本文介绍了所选择的技术方案，所使用的算法和所获得的结果。
A prototype of digital frequency multiplexing electronics allowing the real time monitoring of microwave kinetic inductance detector (MKIDs) arrays for mm-wave astronomy has been developed. It requires only 2 coaxial cables for instrumenting a large array. For that, an excitation comb of frequencies is generated and fed through the detector. The direct frequency synthesis and the data acquisition relies heavily on a large FPGA using parallelized and pipelined processing. The prototype can instrument 128 resonators (pixels) over a bandwidth of 125 MHz. This paper describes the technical solution chosen, the algorithm used and the results obtained.
