Brief Description

To meet the requirements of advanced communications systems, a vector signal generator needs a powerful baseband section. The R&S^®SMW200A sets standards in this field too. Each of the two available baseband modules contains a realtime coder and an arbitrary waveform generator.

An R&S^®SMW-B10 baseband module provides 120 MHz RF bandwidth and 64 Msample ARB memory as standard. The performance can be further enhanced to 160 MHz RF bandwidth and up to 1 Gsample ARB memory via software options.

The bandwidth of up to 160 MHz covers modern digital standards, such as LTE‑Advanced and WLAN IEEE 802.11ac, as well as wideband multicarrier or multistandard radio signals.

The baseband signals can be digitally added, provided with a frequency offset and varied in power and phase relative to each other. This makes it incredibly simple to generate multicarrier scenarios and combinations of different digital standards with the R&S^®SMW200A.

The R&S^®SMW200A uses software options to generate signals for all important digital standards, particularly LTE/LTE‑Advanced, 3GPP FDD/HSPA/HSPA+, GSM/EDGE/EDGE Evolution, TD‑SCDMA and WLAN IEEE 802.11a/b/g/n/ac.

For more information, go to the page describing digital standards options via the Options tab on this page.
