Measure the impossible

FSWX signal and spectrum analyzer

In today’s fast-paced technological landscape, having a reliable and efficient signal analysis solution that can transcend the limits and overcome the limitations of traditional measurement methods is crucial. The cutting-edge multipath FSWX architecture brings a new level of performance and precision to signal analysis.  By applying preselection, suppressing inherent noise and spurious signals and minimizing unwanted artifacts, the FSWX ensures that the true characteristics of the signal under test are accurately captured and analyzed.

特性和优点

Multiple input ports

Phase coherent capture at the same or at different frequencies

The ability to capture wideband, modulated phase coherent signals at the same or different frequencies opens up new measurement scenarios. The FSWX is the first multichannel signal and spectrum analyzer to do so.

  • Compare the output signal of an amplifier or mixer with the modulated reference signal from the input
  • Easily measure the phase relation between individual antennas of a beamforming radar or a MIMO communications system for new insights into the system under test
  • Simultaneous capture at different frequencies in electronic warfare scenarios involving DRFM or radar transmitters for comprehensive situational awareness and improved threat detection capabilities.

Multiple input ports allow for phase coherent capture of multiple signals. This example shows a comparison of the amplitude and phase of two phased array antenna ports as well as the group delay.

Cross-correlation

Measure noise level down to the physical limit

The FSWX is the first signal and spectrum analyzer with cross-correlation. Cross-correlation cancels the inherent noise of the analyzer and gives a clear view on the device under test. With cross-correlation, you can push the noise level down to the physical limit for higher dynamic range in noise, phase noise and EVM measurements or spur searches. Benefits include:

  • Unprecedented sensitivity
  • Lowest possible phase noise
  • Widest dynamic range
  • Best EVM
  • Unmatched level accuracy at low power levels

Cross-correlation eliminates the analyzer’s inherent noise and provides an unobstructed view of the signal. Without cross-correlation, the spectrum re-growth of the amplifier under test would not be visible in this example.

Wideband ADCs

Up to 8 GHz analysis bandwidth

The FSWX has been designed as a wide bandwidth instrument. Each analog signal path is terminated by high-resolution, high-speed ADCs providing 8 GHz of analysis bandwidth. This concept includes:

  • Full analysis BW at all input frequencies
  • Highest sweep speed in spectrum mode
  • High dynamic range for EVM measurements and spur search

Filter banks

Default filter banks with optional YIG preselector

The FSWX features filter banks with independent highpass and lowpass filters across the whole instrument frequency range. Benefits of filter banks vs swept preselection filters include:

  • Highest level accuracy across the entire frequency range
  • Preselected I/Q analysis. Signals at other frequencies are rejected and do not fold as image into the frequency range of interest
  • Fastest sweep speed
YIG filters are available as an option for greatest dynamic range demands.
