High-frequency signal generators

12 October 2011 Test & Measurement

Rohde & Schwarz has enhanced its analog SMB100A mid-range signal generator by adding new frequency options. The SMB-B120/B120L and SMB-B140/B140L options (L versions without step attenuator) enable the generator to cover the frequency range from 100 kHz to 20 GHz and 40 GHz, respectively.

The SMB100A can now handle everything from analog RF to microwave applications.

In the new frequency ranges, the SMB100A still offers a wide dynamic range of

-120 dBm to +14 dBm as standard. New high-power options – the SMB-B31 (for the 20 GHz model) and the SMB-B32 (for the 40 GHz model) – make it possible to achieve an output power of up to +25 dBm. The new options allow users to skip the practice of looping in an external amplifier to achieve higher output power. This technique is now needed only when compensation is required to deal with attenuation in the test setup.

Even at low frequencies, the SMB100A has very low single sideband phase noise thanks to an expanded attenuator range and the direct digital synthesis (DDS) method. These two features mitigate the need for down-conversion.
