Digital Correlation ECE Measurement Technique with a Gigahertz Sampling Digitizer

Abstract

The concept of digital correlation electron cyclotron emission (ECE) measurement is proposed for studying of the mesoscale phenomena. The recent progress in fast sampling and computing enables the acquisition of waveforms of intermediate frequency (IF) in the range of several gigahertz. Correlation analysis using an IF digitizing technique can be helpful for analyzing mesoscale phenomena. This paper discusses the concept and characteristics of the IF digitizing technique for correlation analysis, and presents an example of IF waveform acquisition of ECE.
