4.8 Satellite Identifier
The spectrum analyser makes easier the fieldwork for engineers when working
with SNG mobile units and VSAT communications, since it allows adjusting
transmission-reception systems. It also has several functions to identify satellites
that avoid any possibility of error. When the signal is locked it identifies the
satellite and shows on screen its name.
Often satellite operators request to look for the " Beacon " signal, as a method of
satellite identification. This signal is easily identified by the equipment, because it
has high resolution, high sensitivity and short sweep times.
Below are two BEACON screenshots signals, with a span of 10 MHz and a
bandwidth of 100 kHz resolution, all with a sweep time of 90 ms.
