Applications

R&S®FSV-K7S FM stereo measurement application

The R&S®FSV-K7S option expands the functionality of the R&S®FSV-K7 option by providing measurements on FM stereo transmitters.

An integrated stereo decoder measures the frequency deviation of the channels left, right, mono and stereo as well as the pilot and RDS carrier. The variety of analysis capabilities is expanded to include THD measurement, time-domain analysis (oscilloscope mode display) and frequency-domain analysis (AF spectrum) of the corresponding channel. To perform standard-compliant S/N ratio measurements, both the compulsory audio filters and the quasipeak detectors are available. A clear result summary displays the numeric results for all the measurement channels at the same time and thus enables crosstalk attenuation measurements without having to switch between channels. This means that all measurements necessary on FM stereo transmitters can be performed with the R&S®FSV-K7S option.

Comprehensive measurement functions for complete FM stereo analysis

  • Frequency deviation measurement in channels MPX, L, R, M, S and frequency deviation measurement of the pilot and RDS carrier
  • Crosstalk measurement
  • Carrier power and carrier frequency measurement
  • Audio frequency measurement
  • Absolute and relative deviation measurement for easy-to-perform S/N ratio and crosstalk attenuation measurement
  • AF spectrum display and per channel
  • Up to 4 measurement windows

A variety of audio filters and detectors for standard-compliant measurements

  • ITU-R filter, weighted and unweighted
  • Highpass filters 20 Hz, 50 Hz, 300 Hz and lowpass filters 3 kHz, 15 kHz, 23 kHz and 150 kHz
  • Selectable deemphasis 50 µs, 75 µs, 750 µs
  • Detectors: +/-peak/2, + peak, -peak, RMS, RMSxSQR2, quasi peak (in line with ITU-R 468) and quasi peakxSQR2

Built-in THD measurement

  • Automatically tuned to the fundamental
  • Simultaneous display of SINAD and THD values
  • Selective THD measurement of individual harmonics using marker functions in the AF spectrum display

R&S®FSV Signal and Spectrum Analyzer Applications

The result summary clearly displays the measurement results of all the channels; further switchover is not required. Additional displays such as the mono signal or the MPX spectrum display support further analysis.
