Spectrum analysers target 5G NR technology

As 5G New Radio (NR) progresses, manufacturers of RF components, transmitters and modules face complex measurement tasks on wideband RF signals. Engineers need to analyse wireless communications signals in R&D and production to support 5G bandwidth test and RF requirements. To meet these demands, Rohde & Schwarz introduces two mid-range signal and spectrum analysers, the R&S FSV3000 and R&S FSVA3000.

The R&S FSV3000 is designed to help users set up complex measurements simply and quickly in labs and on production lines. It provides up to 200MHz analysis bandwidth, which is sufficient to capture and analyse, for example, two 5G NR carriers at once.

The R&S FSVA3000 has up to 400MHz analysis bandwidth, a high dynamic range and a phase noise of -120dBc/Hz. Users can perform demanding measurement applications such as linearising power amplifiers, capturing short events and characterising frequency agile signals.

Both the R&S FSV3000 and R&S FSVA3000 can measure EVM values better than one per cent for a 100MHz signal at 28GHz. Combined with the coverage of the 5G NR frequency bands up to 44GHz, Rohde & Schwarz says the analysers are particularly suitable for analysing 5G NR signals.

The R&S FSV3000 and the R&S FSVA3000 spectrum analysers simplify troubleshooting rare events and setting up complex measurements. The event-based action graphics user interface (GUI) means that whenever a pre-determined event occurs the corresponding action, such as saving a screenshot or I/Q data, is performed.

Auto measurements shorten instrument set-up time. Parameters such as centre frequency, span and amplitude reference are automatically set based on the applied signal. For a pulse signal, the gate sweep parameters are set. For standard-compliant measurements such as ACLR or SEM, the auto measurement feature selects the corresponding standard parameter table.

For automated production lines with complex measurements, external computers can control of the instruments via SCPI commands. The embedded SCPI recorder makes it much easier to create executable scripts, since all manual input is translated into plain SCPI or into the syntax of common programming languages or tools such as C++, Python or MatLab.

The R&S FSV3000 and R&S FSVA3000 both interact with cloud based processing. The optional 10Gbits per second LAN interface enables I/Q data transfer toward the network end even at high sample rates, which is required for wideband signal analysis such as for 5G.

The R&S FSV3000 and R&S FSVA3000 are available now.
