- Connections between the R&S®SGS100A and the R&S®SGU100A.
When the R&S®SGS100A and the R&S®SGU100A are connected, they act as a single instrument for both remote control and manual operation via the R&S®SGMA-GUI PC software. The R&S®SGU-Z4 extension kit provides the required electrical connections and mechanical stabilization on the front and rear panel. The combined instruments offer the same connections as the R&S®SGS100A itself: one RF output for the entire frequency range and one analog I/Q input for vector modulation.
In this setup, tasks are spread automatically and transparently between the two instruments so that users feel as if they are operating one instrument instead of two.
When connected via LAN or PCIe, the R&S®SGU100A is controlled completely via the R&S®SGS100A. The R&S®SGMA-GUI PC software displays the R&S®SGU100A as an extension to the R&S®SGS100A and adjusts the maximum settable frequency range.
Equipped with the R&S®SGU100A, the R&S®SGS100A covers the entire frequency range from 10 MHz to 40 GHz without modulation, and from 80 MHz to 40 GHz with vector modulation.
With two height units and ½ 19" rack width (or one height unit and full 19" rack width), the combination of the R&S®SGS100A and the R&S®SGU100A provides the lowest form factor on the market for 20 GHz vector signal generation. This is particularly important for applications with limited rack space, such as in production or in system setups.
The instruments are designed for continuous operation and feature low energy consumption. With power consumption less than 110 W, the combination is ideal for use in locations without direct access to normal power supply where battery operation using a DC converter is required.

- EVM performance measurement using the R&S®SGS100A/R&S®SGU100A combination driven by an R&S®AFQ100A at 14 GHz.
The instrument combination has a small form factor yet offers high performance. For example, 0.5% error vector magnitude for a QPSK signal with 30 Msymbol/s and a center frequency of 14 GHz.
Above 12 GHz, the R&S®SGU100A features an I/Q modulation bandwidth of 2 GHz, making it ideal for very wideband aerospace and defense applications with extremely short pulses.
Beamforming applications and phased antenna array systems require high-quality phase-coherent test signals. The R&S®SGU100A provides the ideal framework for these tasks. The instruments can be connected with a very precise 1 GHz reference frequency and the synthesizers of multiple instruments can be coupled using the phase coherence option. As a result, the relative phases remain stable over a long time period.
