Rohde & Schwarz and Zurich Instruments will present advanced test and measurement solutions for photonics at the LASER World of PHOTONICS tradeshow in Munich. Highlighted solutions include the R&S FSPN and R&S FSWP, two exceptionally powerful phase noise analyzers for characterizing laser systems. Visitors can also see demos of the R&S MXO 4 and R&S RTO6 oscilloscopes from Rohde & Schwarz as well as the Quantum Computing Control System (QCCS) and lock-in amplifiers from Zurich Instruments.

The R&S®FS-SNS smart noise source enables accurate noise figure and gain measurements by automatically loading all necessary setup parameters. Learn more here.

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.

Technical specifications of the R&S®FSWP phase noise analyzer and VCO tester.

The R&S®FSWP phase noise analyzer and VCO tester features very high sensitivity thanks to extremely low noise internal sources and cross-correlation. It can measure phase noise on highly stable sources such as those found in radar applications in just seconds. Additional options such as pulsed signal measurements, residual phase noise characterization and integrated high‑end signal and spectrum analysis make the R&S®FSWP a unique test instrument. A multitouch display ensures straightforward and intuitive operation. The embedded SCPI recorder enables easy creation of executable scripts.
