摘要
欧空局Planck卫星上的低频仪器（LFI）搭载了十一个辐射计子系统，称为辐射计链组件（RCA），每个组件由一对伪相关接收机组成。我们描述了为鉴定飞行模型RCA并测量其发射前性能而进行的地面校准活动。每个RCA在专用的类飞行低温环境中进行校准，辐射计前端冷却至20K，后端冷却至300K，外部输入负载冷却至4K。将模拟不同温度黑体的匹配负载置于天空喇叭前，以推导基本辐射计特性，如噪声温度、增益和噪声性能（例如1/f噪声）。测量了每个探测器的频谱响应及其对热变化的敏感性。所有十一个LFI RCA均已完成校准。在这些测试中测得的仪器参数，如噪声温度、带宽、辐射计隔离度和线性度，为Planck-LFI数据分析提供了关键输入。
