Key facts
The R&S®SGU100A SGMA upconverter offers a frequency extension to 40 GHz. 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. The combined instruments offer the same connections as the R&S®SGS100A: one RF output for the entire frequency range and one analog I/Q input for vector modulation. In this setup, tasks are automatically distributed between the two instruments so that users feel as if they are operating a single instrument.
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.
One RF output for the entire frequency range
When the R&S®SGS100A and the R&S®SGU100A are connected, they act as a single instrument. The R&S®SGU-Z4 extension kit provides the required electrical connections and mechanical stabilization. The combined instruments offer the same connections as the R&S®SGS100A: one RF output for the entire frequency range and one analog I/Q input for vector modulation.
In this setup, tasks are spread automatically between the two instruments.

Seamless integration into existing user interfaces
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.

Lowest form factor and power consumption on the market
With two height units and 1/2 19" rack width (or one height unit and full 19" rack width), the combination of R&S®SGS100A and R&S®SGU100A provides the lowest form factor on the market for 20 GHz vector signal generation. This is important for applications with limited rack space, such as in production or in system setups. The instruments are designed for continuous operation and have low energy consumption of less than 110 W.
Optimized from factor
High performance up to microwave frequencies
The instrument combination has a small form factor yet offers high performance with a 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.
EVM performance
EVM performance measurement using the R&S®SGS100A/R;&S®SGU100A combination driven by an R&S®AFQ100A at 14 GHz.
Scalable multi-instrument setups for demanding tasks
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.
Synchronized phase stability
