Key facts

  • 200 MHz fading bandwidth
  • MIMO fading simulation with up to 32 fading channels
  • Pre-defined channel models for all important digital standards

Brief description

The internal realtime fading simulator of the R&S®SMW200A is a cost-effective solution for testing the behavior of devices under realistic transmission conditions.

A single R&S®SMW-B15 hardware fading module can simulate a SISO fading channel with up to 20 individually configurable fading paths. Predefined settings for digital communications standards such as 5G NR, LTE, 3GPP FDD, GSM, CDMA2000, or WLAN ensure simulation of standard compliant fading scenarios.

The R&S®SMW200A can be equipped with up to four powerful R&S®SMW-B15 fading options, allowing up to 32 fading channels to be generated simultaneously (e.g. for MIMO applications).
