Geodetic VLBI system amplifies the signal of particular band.
The signals of S-band, X-band, K-band and Q-band are measured by this system in the same time.
Data processing units
Backend system converts analog signal into low-frequency band signal and saves the signal of selected channel in the storage. PCLA and E/O are installed in antenna cabin. O/E, IF selector, formatter, recorder and S/W correlator are installed in observation building.
