Rohde & Schwarz—Vector Signal Generator Expanded (Microwave)

[SatNews] The R&S SGU100A RF upconverter from Rohde & Schwarz extends the frequency range of the R&S SGS100A vector signal generator from 12.75 to 20GHz—by combining the two instruments, users can now generate vector signals continuously from 80MHz to 20GHz, e.g, for use in test systems in the aerospace and defense sector.   

Once combined, the R&S SGS100A and R&S SGU100A act as a single unit with one I/Q input and one RF output. This combined unit can also be controlled remotely or manually just like a single instrument. Depending on the configuration, it takes up two height units at ½ 19-inch width or one height unit at 19-inch width. The R&S SGS100A and R&S SGU100A together take up considerably less space in the rack than other, comparable microwave vector signal generators, while still offering outstanding performance. For example, the error vector magnitude (EVM) for a 30Msym/s QPSK signal is 0.5 percent at an RF frequency of 14GHz. Above 12GHz, the R&S SGS100A with the R&S SGU100A features an I/Q modulation bandwidth of 2GHz. This provides an ideal solution for wideband applications such as those used in satellite communications or radar tests requiring extremely short pulses.   

The R&S SGU100A is available as a pure CW source or as a source for I/Q-modulated signals. Especially when using the CW version, the combination of R&S SGS100A and R&S SGU100A is optimal for multitone applications requiring phase coherence. Users who already have an R&S SGS100A up to 12.75GHz or another signal generator with a similar frequency range can use the R&S SGU100A to extend their generator's frequency range up to 20GHz.   

The R&S SGU100A RF upconverter is now available from Rohde & Schwarz. For more information, please visit http://www.rohde-schwarz.com/ad/press/sgu100a.
