Key facts

  • Fully calibrated solution
  • Ease of operation
  • Integrated to base units
  • Smart accessories
  • Compact form factor

Frequency extension to 110 GHz

The R&S®FE110ST extends the frequency of the R&S®SMW200A, the R&S®SMM100A and the R&S®SFI100A vector signal generators to the frequency range from 70 GHz to 110 GHz. After connection via LAN interface the frontend is fully integrated to the firmware of the base units. This ensures an easy-to use and calibrated solution which acts like one instrument. Plug it in and start designing and testing the next generation automotive radar or mobile communications today.

Features & benefits

Fully calibrated solution

The R&S®FE110ST is designed as an external frontend for the R&S®SMW200A, R&S®SMM100A and R&S®SFI100A vector signal generators. Every R&S®FE110ST is fully characterized during production. As soon as the R&S®FE110ST is connected via LAN, the correction data in the frontend automatically transfers to the base unit, ensuring a fully calibrated signal generation solution and reducing the time and equipment needed for setup and calibration while enhancing measurement fidelity.

Ease of operation

The R&S®FE110ST fits seamlessly into the operating concept of the R&S®SMW200A and R&S®SMM100A vector signal generators. As soon as the frontend is connected with a LAN, IF and  reference frequency, the R&S®SMW200A and R&S®SMM100A are converted into signal generators for the frequency range between 70 to 110 GHz. Setting up automated measurements is easy and reliable as the remote commands stay the same.

Excellent signal performance

Generating wideband-modulated signals with excellent modulation quality is essential when developing products for next generation automotive radar or mobile communication. The R&S®FE110ST has outstanding modulation quality. A  5G NR signal with a channel bandwidth of 2 GHz (960 kHz SCS) and QPSK modulation can be analyzed with an EVM better than -39 dB (at 88 GHz). This excellent modulation quality is maintained over a wide dynamic range.

Smart accessories

External bandpass filters optimize spur performance and are available as options for the R&S®FE110ST and R&S®FE110SR. The R&S®FE110-Zxx waveguide bandpass filters have low insertion loss and an excellent voltage standing wave ratio. Device characteristics are stored on an EPROM which is automatically considered by the base units for a fully calibrated solution. Additional accessories like waveguide adapters (R&S®FE110-Z20), antennas or coax adapter to 1 mm are also available.

Compact form factor

The compact design allows the R&S®FE110ST to be positioned closely to the device under test. This minimizes the length of additional RF feed lines that can increase losses. Short distance to the DUT reduces the level ripple over frequency and improves signal quality. The R&S®ZZA-FE01 frontend height adjustement has adjustable feet and versatile mounting points which allow flexible positioning of the R&S®FE110ST in a chamber.
