Keep up-to-date in 5G development

In-depth 5G physical layer signal analysis  

• The FSW scalable, wide internal analysis bandwidth of up to 8.3 GHz allows you to capture the entire bandwidth of the downlink signal and evaluate the complete system.
• R&S®FSW-K144 and R&S®FSW-K145 options cover downlink and uplink in-band measurements of 3GPP 5G NR. Each signal subframe is analyzed and a wide range of measurement results are provided, including the EVM, frequency and power of different channels and signals.

Powerful vector signal analysis application

Digital signal analysis  

The R&S®FSW-K70 vector signal analysis option enables users to flexibly analyze digitally modulated single carriers down to the bit level. The clearly structured operating concept simplifies measurements despite a wide range of analysis tools.The R&S®FSW-K70M allows analysis of signals with two different modulation schemes, such as DVB-S2X signals.The R&S®FSW-K70P extension measures the raw bit error rate (BER) on PRBS data up to PRBS23.
