Two new frequency options, the R&S SMB-B112 and R&S SMB-B112L, elevate the R&S SMB100A analog signal generator from Rohde & Schwarz to new levels of performance. Both now cover an exceptionally wide frequency range from 100 kHz to 12.75 GHz. In addition, the R&S SMB-B112 option equips the R&S SMB100A with a wear-free electronic step attenuator. No other signal generator in the frequency range up to 12.75 GHz has this feature. An electronic step attenuator is particularly beneficial when the generator's level settings must be changed frequently. In production lines or in automated test equipment (ATE) systems, it ensures, for example, the required high switching speed and withstands heavy wear.

When equipped with the R&S SMB-B112 / R&S SMB-B112L option, the R&S SMB100A can perform the blocking tests that are specified in many telecommunications standards. In these tests, the useful signal at the receiver is subjected to interference from a CW signal on a frequency up to 12.75 GHz. The R&S SMB100A can also be used as an RF source for tests on X band radar equipment and in a variety of other applications. Like the models that operate up to 6 GHz, the 12.75 GHz signal generators of the R&S SMB100A family also feature a very high output level as standard, outstanding RF characteristics and low cost of ownership.

The R&S SMB-B112 option (with electronic step attenuator) and the R&S SMB-B112L option (without electronic step attenuator) for expanding the frequency range of the analog R&S SMB100A are now available from Rohde & Schwarz.
