r&s®smw-55体育

• up to eight individually configurable baseband signals
• settable frequency, level and phase offsets for each baseband signal
• realtime addition of signals for easy generation of multi-carrier and interference scenarios
• 8x siso signal generation, optionally with fading
• optional awgn for each channel
• 2x2 mimo channel simulation for three or four separate entities (with 4xr&s^®smw-b14, r&s^®smw-k74)
• coupling of baseband signals for simplified signal configuration of multi-cell diversity and mimo scenarios
• flexible routing of baseband signals to two rf outputs, two analog and six digital iq outputs (depending on instrument and system configuration)
• additional rf paths via up to six digitally connected r&s^®sgt100a
• additional microwave rf paths via r&s^®sgs100a r&s^®sgu100a

multi-standard-radio applications, interference scenarios, lte carrier aggregation, multi-emitter radar simulation and phase coherent beam forming all require simultaneous generation of a multitude of baseband and rf signals.

the r&s^®smw-k76 “multiple entities” option enables generation of up to eight different baseband signals from a single r&s^®smw200a. together with additional digitally connected r&s^®sgt100a vector rf sources, the r&s^®smw200a is turned into a versatile eight channel vector signal generator. connection of analog r&s^®sgs100a rf sources and r&s^®sgu100a up-converters for applications in the microwave range is also supported.

with additional r&s^®smw-b14/r&s^®smw-b15 fading hardware modules, up to 8x siso fading is possible. together with the r&s^®smw-k74 mimo option, 4x2x2 and 3x2x2 mimo scenarios are supported. this e.g. allows simulation of up to four aggregated lte carriers or four different cells with 2x2 mimo from one r&s^®smw200a.

the r&s^®smw-k76 option requires two r&s^®smw-b10 options and an r&s^®smw-b13t option as prerequisite.
