R&S®FSW-K70 Vector signal analysis

The R&S^®FSW-K70 option enables users to flexibly analyze digitally modulated single carriers down to the bit level. The clearly structured operating concept simplifies measurements, despite the wide range of analysis tools.

• Modulation formats:
  • 2FSK, 4FSK, 16FSK, 32FSK
  • MSK, GMSK, DMSK
  • BPSK, QPSK, Offset-QPSK, DQPSK, 8PSK, D8PSK, π/4-DQPSK, 3π/8-8PSK, π/8-D8PSK
  • 16QAM, 32QAM, 64QAM, 128QAM, 256QAM, 512QAM, 1024QAM, 2048QAM, 4096QAM
  • 16APSK (DVB-S2), 32APSK (DVB-S2), 2ASK, 4ASK, π/4‑16QAM (EDGE), –π/4-16QAM (EDGE), SOQPSK
• Analysis length up to 64 000 symbols
• 10 MHz internal signal analysis bandwidth (optionally 40/80/160/320/512/1200/2000 MHz and 5 GHz)

The visualization of the demodulation stages and the associated settings is so clear that even beginners and infrequent users can find the correct settings.

Based on the description of the signal to be analyzed (e.g. modulation format, continuous or with bursts, symbol rate, transmit filtering), the R&S^®FSW-K70 option helps users automatically find useful settings.

• Display choices for amplitude, frequency, phase, I/Q, eye diagram; amplitude, phase or frequency error; constellation or vector diagram
• Analysis of RF signals or analog and digital baseband signals
• Statistical evaluations
  • Histogram representation
  • Standard deviation and 95th percentile in the result summary
• Spectrum analyses of the measurement and error signal considerably support users in finding signal errors such as incorrect filtering or spurious emissions
• Flexible burst search for the analysis of complex signal combinations, short bursts or signal mix – capabilities that go beyond the scope of many signal analyzers
• Bit error measurements on PRBS data or on known data sequences
• Equalizer helps in finding the optimum filter design
