R&S FSL series spectrum analyzers

  • Frequency range 9kHz to 3GHz, 6GHz or 18GHz
  • Optional tracking generator
  • Large signal analisys bandwidth (28MHz)
  • Light weight (8kg)
  • Low measurement uncertainty, even in microwave range

The R&S FSL series spectrum analyzers consists of 3 models: the FSL3 with a bandwidth of 9kHz to 3GHz, the FSL6 with a bandwidth of 9kHz to 6GHz, and the top model: the FSL18 with a bandwidth of 9kHz to 18GHz. A Tracking generator is optionally available for all models.

The FSL units are striking because of their compact size and minimal weight. Given the functionality, you may see it as a laboratory instrument, but this unit only weighs 8 kg. There is even a possibility to run the unit with a battery option, so you can even perform a wide variety of measurements on remote locations.

Options FSL spectrum analyzers

Depending on the specific measurements you want to perform, there is a wide range of options available.
