The first AliCPT-1 module incorporates two 4-6 GHz μmux readout lines, each with a multiplexing factor of 910, to readout 1,704 TES bolometers and additional dark channels. The module is probed via an RFSoC-based room-temperature electronics system, which combines all tone generation and processing procedures on a single piece of hardware. Here we describe the integration of the module and electronics with the receiver and conduct end-to-end laboratory testing of their performance. Module measurements include spectra, optical efficiency, polarization efficiency, near-field beam maps, and sensitivity to external magnetic fields. We evaluate the behavior of the readout system during optical data collection, including its noise performance. |
