Two different spectrometry systems in the terahertz band are described, characterised and used:
the Tera K8 Time-Domain THz Spectrometer from Menlo Systems, which works in the time domain,
and the TeraScan 780 Frequency-Domain Terahertz Platform from Toptica, which works in the
frequency domain. The set-up for which the optimal performance of each system is obtained is
presented, together with spectroscopy measurements obtained with them.
