Abstract

The paper presents a method for determining the limits of the frequency spectrum of a pulsed terahertz (THz) spectrometer with a radiation generator based on an InAs crystal in a magnetic field and with a photoconductive antenna as detector. It is shown that the spectral measurements that are carried out are reliable within the limits of the given frequency interval. A THz radiation detector based on an iPCA-21-05-1000-800-h photoconductive antenna when a signal was recorded from the same source demonstrated a band in a working range from 0.017 to 1.6 THz. The method can be used for pulsed THz spectrometers with various generators and detectors of THz radiation.
