Rohde & Schwarz FSWX3044 (1348.0000.42)

Multiple Input Ports

(Phase coherent capture at the same or different frequencies)

Being able 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 amplifier or mixer output signal 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.

- Simultaneous capture at different frequencies in electronic warfare scenarios with DRFM or radar transmitters for the improved threat detection capabilities.

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.

Cross-correlation lets you push the noise level down to the physical limit for the 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

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 with 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

Note: YIG filter are available as an option for greatest dynamic range demands.
