Based on a scalable hardware platform for the future of RF parameters of the two separate transmit path and the receive path, the frequency range up to 6 GHz and to 80 MHz transmission bandwidth / reception bandwidth to 40 MHz, making R & S? CMW500 can perfectly meet the current and future application requirements. 128 dB wide dynamic range and sensitivity input output, reducing the need for external amplifiers or attenuators needs. RF signal source can be extended depending on the application, using one or two RF paths contain RF converter and RF front-end. The front end can be achieved with a direct connection with complex RF architecture of wireless devices. ? Therefore, R & S CMW500 for the following test: J test has MIMO functionality DUT J parallel tests using the same technology in parallel testing a DUT DUT J Two Technological optional baseband and signaling unit Analyzer module and up to two ARB baseband generator for non-signaling mode. In addition, it can integrate multiple signaling unit, which provides network emulation and protocol signaling test.
