The R&S SMW200A from Rohde and Schwarz is a touch screen vector signal generator that operates from 3 or 6 GHz. It can provide up to 18 dBm of an output power, has a phase noise of -139 dBc/Hz and a setting time of 1 ms. The R&S SMW200A is ideal for generating complex, digitally modulated signals for the communication, aerospace and defense sectors. The Fading scenarios such as 2x2 MIMO, 8x2 MIMO for TD-LTE and 2x2 MIMO for LTE-Advanced carrier aggregation can be simulated easily. It can also be equipped with an optional second RF path for frequencies up to 6 GHz.
