Key facts

  • Extended signal analyzer and vector signal generator frequency ranges
  • Covered frequency range from 24 GHz to 50 GHz
  • Minimized cable losses due to up and downconversion directly at the DUT  
  • Increased test setup performance
  • 3-year warranty extension

Signal generation and analysis at the device connection

R&S®FExx external frontends extend the frequency ranges of Rohde & Schwarz signal and spectrum analyzers and signal generators up to 50 GHz. The R&S®FExx enables the up and downconversion of the signal directly at the DUT. In an OTA environment it lowers cable losses, increases sensitivity and delivers more power at the antenna.

Features & benefits

Easy control

Integration and transparent control with R&S®FSV3000, R&S®SMM and R&S®SMW firmware

R&S®FExx frontends are fully controlled by R&S®FSV3000, R&S®FSVA3000, R&S®SMM and R&S®SMW firmware. This enables a transparent and easy use in both manual and automated setups. Calibration data that has been generated during the production process is automatically used to provide the lowest measurement uncertainty.

Extend the frequency range for 5G testing

Enables extension from FR1 to an FR2 test system

As 5G FR2 becomes more popular, R&S®FExx frontends can extend the frequency range of lower frequency FR1 setups in existing an R&S®FSV3000, R&S®FSVA3000, R&S®SMM or R&S®SMW to cover 3GPP FR2 frequencies.

Excellent RF performance for setup

R&S®FExx frontends have excellent transmit and receive signal quality for a high-performance, cost-efficient solution

The built-in, high-performance R&S®FE44S VCO has the lowest phase noise to generate signals with the highest fidelity. . 
The EVM is well below 1% (–40 dB) over a wide range. Signals generated on the transmit side have similar performance.
