Vector signal generators (VSGs) capable of simulating the complex fading scenarios of military communications systems can be found at the 2012 IMS, courtesy of Rohde & Schwarz (booth No. 2415). With its recently announced R&S SMU-K77 option, the model R&S SMU200A VSG can perform simulation of dynamic fading, as well as the effects of multipath signal propagation. The instrument can mimic different Doppler effects, such as those found from communications towers to aircraft and from ship to ship. The VSG operates from 100 kHz to 2.2 GHz, 3.0 GHz, 4.0 GHz, or 6 GHz for the first RF path (depending on model), with a second path capable of operating to 2.2 or 3.0 GHz. In addition to performing military-type fading simulations, the instrument supports testing of all modern communications standards, such as LTE and WiMAX.
