The R&S SMB100A - SMB-B101 RF signal generator with a frequency range up to 1.1 GHz 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/φM 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.
All important analog modulations with AM, FM/φM 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.
