Rohde & Schwarz FS-K4

Phase Noise Measurement Software FS-K4 extends the measurement capabilities of Rohde & Schwarz Spectrum Analyzers to give a phase noise tester.

R&S FSE, FSIQ, FSU, FSP and FSQ are for this purpose because of their low inherent phase noise and noise figure.

The high phase noise measurement speed is achieved through the high sweep rates of all analyzers.

<

p>It is possible to trade off speed against accuracy at small resolution bandwidths (<1kHz) by using either FFT or digital filters.

The software allows different settings within a phase noise diagram, e.g. FFT close to the carrier and analog/digital filters far off the carrier.

The software FS-K4 runs on the FSE with the Controller Function FSE-B15 fitted (Windows NT), or on an external PC (Windows 9x or later) with GPIB controller.
