Key facts

  • Up to 10 GHz RF modulation bandwidth
  • ARB with up to 8 GSample memory
  • IF output from 11 GHz to 21 GHz
  • Wideband direct DAC, differential and single-ended analog I/Q outputs
  • Full integration with R&S®FE110ST and R&S®FE170ST frontends

The essential foundation for your sub-terahertz solution

The R&S®SFI100A wideband IF vector signal generator satisfies bandwidth needs for demanding applications such as early 6G research, millimeter-wave WLAN and automotive radar. The compact instrument has a very wide RF modulation bandwidth of up to 10 GHz and generates fully calibrated RF signals. The R&S®SFI100A connects seamlessly with the R&S®FE110ST and the R&S®FE170ST up-conversion frontends to cover the frequency range from 70 GHz to 175 GHz. It fully controls a connected frontend and the solution can act as a single instrument. In addition to the RF interface, the R&S®SFI100A also has analog IQ outputs for wideband signal generation in the baseband.

Features & benefits

Flexibility for various test scenarios

Test at sub-terahertz frequencies, IF and in baseband

The R&S®SFI100A is flexible enough for various test scenarios: IF tests from 11 GHz to 21 GHz and RF tests from 70 GHz to 175 GHz together with the R&S®FE110ST and the R&S®FE170ST external frontends. The R&S®SFI100A offers wideband single-ended, differential and direct DAC analog I/Q signals for baseband tests with best signal quality up to 5 GHz and up to 2 V (Vpp). Flexibility is vital for demanding test setups like those in the early research phases of 6G.

Extensive flexibility for all your test needs
Open Lightbox

Extensive flexibility for all your test needs

The R&S®SFI100A covers IF tests from 11 GHz to 21 GHz and sub-THz frequencies from 70 GHz to 175 GHz with frontends.

Fully calibrated sub-terahertz solution

Seamless integration with R&S®FE110ST and R&S®FE170ST frontends

Thanks to full integration and control, the R&S®SFI100A knows the characteristics of a connected R&S®FE110ST or R&S®FE170ST frontend and automatically includes them for calibrated signals at the measurement plane. The setup can seamlessly be extended to cables and connected smart accessories such as bandpass filters and power amplifiers, reducing measurement uncertainty and enhancing measurement fidelity, even in the sub-THz frequency range.

Full frontend integration

Full frontend integration

The R&S®SFI100A has native frontend support in the firmware for full set-up integration and control from a single interface.

Unparalleled performance

Excellent modulated signal quality

The R&S®SFI100A has unparalleled wideband modulation signal quality. An outstanding EVM of less than –41 dB (< 1 %) is possible over a wide output power range for a 2 GHz-wide 5G NR signal with a 16 GHz center frequency. The modulation quality remains excellent when the R&S®SFI100A is combined with a frontend (see EVM bathtub curve). The outstanding performance lets you test the real performance of the DUT.

Even at 144 GHz, an outstanding EVM of less than –34 dB (2 %) can be achieved for a 4 GHz wide IEEE 802.11ay signal over a wide power range.

Enhanced usability

Automation made easy

The R&S®SFI100A can be controlled via all common remote interfaces. Users benefits from help functions for programming automatic test sequence controls.  The built-in SCPI macro recorder and code generator supports fast, convenient generation of SCPI program sequences. Code templates help directly generate executable code for MATLAB®, CVI or Python. User-specific templates are also available to minimize the time required for test automation.
