Rohde & Schwarz introduces improved performance for phase noise analysis and voltage-controlled
oscillator (VCO) measurements. Both the high end R&S FSWP phase noise analyzer and VCO tester plus
signal and spectrum analyzer in one instrument, and the R&S FSPN dedicated phase noise analyzer and
VCO tester, are now upgraded. Simultaneous hardware and software upgrades improve the market-leading
performance even further, reducing noise levels and measurement times, and increasing accuracy. Both
analyzers include test sequence recording functions (SCPI recorder), unique for this class of instrument.

The new hardware basis common to both phase noise analyzers includes upgraded DC sources with
reduced noise levels, further enhancing market-leading sensitivity. Users will appreciate the improved
capacitive screen featuring higher color intensity and better antiglare properties, making the display brighter
and clearer in all working conditions. In addition, multi-touch features like zoom are supported by the updated
user interface. For very low noise oscillators with the inherent noise largely thermal at wider offsets, any
potential cross-spectral collapse is now suppressed. In particular for production use, higher measurement
speed for VCO measurements will help reduce the cost of test. With the newly introduced SCPI command
recorder Rohde & Schwarz implements for the first time a function with phase noise measurement
equipment to record sequences of manual settings. Using the command recorder, engineers can create
easily repeatable test sequences, including the necessary synchronization to operate correctly.

The updated R&S FSPN and R&S FSWP phase noise analyzers are now available from Rohde & Schwarz.
