Abstract

We describe the distributed control system that we are developing for the Wideband frontend receiver system for Submillimeter Array (wSMA). This distributed control system is based on an array of Raspberry-Pi (RPi) modules, which is embedded in each subsystem. The RPis run the Linux operating system and they are integrated with Input/Output (I/O) circuits which carry out the control and monitoring functions. The distributed architecture gives rise to a low-cost and yet versatile and powerful setup, which can be built up gradually by adding subsystems, one at a time. In this paper, we will present, in more details, two RPi-controlled subsystems: the Local oscillator (LO) module and the scanning spectrometer.
