Rohde & Schwarz is paving the way for research in the terahertz frequency range by demonstrating multi gigabit data transmission in the D-Band at 140 GHz.
The setup features the R&S FSW high-end signal and spectrum analyser equipped with an R&S FSW-B8001 option, supporting an unparalleled 8.3 GHz internal analysis bandwidth. This new hardware option will be available soon from Rohde & Schwarz.
In the setup, a wideband-baseband signal is upconverted to the selected 140 GHz frequency via a R&S TC RSE converter box.
The world’s leading analog signal generator, the R&S SMA100B, provides the local oscillator frequency to the upconverter.
The transmission is carried out over-the-air, with the converter connected to a horn antenna. The transmitted signal is received via another horn antenna and downconverted.
The R&S FSW featuring the new, unique 8.3 GHz bandwidth option R&S FSW-B8001 analyses the signal, carrying out signal quality measurements such as error vector magnitude (EVM) to assess the performance of the transmission.
Various common modulation formats are demonstrated. The new four-channel power supply R&S NGP800 by Rohde & Schwarz plays a vital role powering various parts and components in this setup.
