The R&S SMB100A series signal generators have a frequency range up to 40 GHz that provides outstanding spectral purity and high output power. In addition to pure CW signals, the R&S®SMB100A also provides the most common analog AM and FM/fM modulation modes as standard. Moreover, the R&S®SMB100A can be equipped with an excellent pulse generator and pulse modulator that makes it possible to generate user-programmable pulse scenarios, also referred to as pulse trains. Key facts. Excellent signal characteristics with low SSB phase noise of typ. -128 dBc (at 1 GHz, 20 kHz offset). High output power of typ. up to +27 dBm. Analog modulations with AM, FM/fM and pulse modulation supported. Frequency extension from 50 GHz to 110 GHz in combination with the R&S®SMZ frequency multiplier. Support of R&S®NRP-Zxx power sensors. Remote control via LAN, USB and GPIB including emulation modes for legacy instruments.
