Abstract
A submillimeter spectrometer using the concept of generating continuosly tunable difference-frequency sideband by beating the HCN laser radiation and millimeter wave klystron radiation in the non-linear Schottky barrier diode has been developed for the accurate frequency measurement on32S16O gaseous sample at 820.151 GHz. The strength of the reradiated signal has been investigated as a function of generating laser and klystron power as well as of the d.c. bias applied externally to the diode.
