Abstract

In this paper we present the design of a hardware module for measurement of power and phase of the 64 channels of the LHCD (lower hybrid current drive) system at 3.7GHz. The power measurement module uses a single IC, LTC5508. The output (in volts) from the IC is then mapped to obtain the power value in dBm and the same is displayed on a computer. Raspberry Pi is used to display the results on a computer in the form of a GUI (graphical user interface). The phase module however incorporates ICs namely, AD8302 (for phase measurement).
