针对QUIJOTE实验30/40 GHz仪器，设计基于树莓派5和MCC 118的模块化校准设备，替代老化的PXI，兼顾精度、易用性与经济性。
AI 中文摘要
QUIJOTE射电天文实验的30和40 GHz仪器使用非常灵敏的接收机，这些接收机需要被表征，以确保其正常运行并用于校准。鉴于迄今为止为此目的使用的PXI-1031DC设备已老化，已提出设计一种新设备，即Calibrator TFGI QUIJOTE。该新设备的设计理念是简单且模块化，易于使用和升级。它基于Raspberry Pi 5系统构建，使用MCC 118作为模拟读取模块。该系统在创客和专业人士中广为人知，不仅满足模块化和易用性的要求，还确保该设备在经济上比PXI更具竞争力。该设备的第一版已构建并测试，在准确性和易用性方面取得了良好结果。
英文摘要
The 30 and 40 GHz instruments of the QUIJOTE radio astronomy experiment use very sensitive receivers which need to be characterized both to ensure their proper functioning and for their calibration. Given the age of the PXI-1031DC device used up until now for this purpose, the design of a new device, the Calibrator TFGI QUIJOTE, has been proposed. This new device has been designed with the idea of being simple and modular, easy to use and upgrade. It is built on a Raspberry Pi 5 system, using an MCC 118 as analog reading module. This system, widely known among both makers and professionals, not only meets the requirements of modularity and ease of use, but also ensures that the device is much more economically competitive than the PXI. A first version of the device has been built and tested, obtaining good results in accuracy and ease of use.
