The release of SignalVu 5G NR analysis software for Tektronix’ 6-Series B mixed-signal oscilloscopes (MSO) gives engineers the ability to perform critical 5G NR measurements, per 3GPP specifications, on the oscilloscopes they rely on to bring-up and characterise new electronic designs.
6-Series B MSO oscilloscopes are used by RF system designers for viewing power rails, digital control buses and I/O signals, in addition to RF signals. Each channel is backed by a digital downconverter that enables spectrum analysis synchronised with time-domain waveforms. This provides engineers with a time-coherent view of the choreography of signals that make up their designs. 5G system designers can now add 5G NR signal analysis to Tektronix oscilloscopes, which enables them to quickly diagnose faulty signal interactions on a single oscilloscope that would otherwise require painstaking correlation between multiple instruments.
In addition to the ability to give a synchronised view of a wide variety of signals, the 6-Series B MSO offers the wide capture bandwidth and low intrinsic noise needed for 5G signal analysis. Offering this performance on oscilloscopes reduces the need for costly, dedicated vector signal analysers.
The new analysis package enables pass/fail testing of the 5G NR physical layer to qualify transmitter designs per the 5G NR standard established under the 3GPP release of 15/16 test specifications. It includes important signal quality measurements such as error vector magnitude (EVM), adjacent channel power (ACP), spectral emission mask (SEM) and power versus time (PVT). Tektronix developed the new 5G NR analysis package using algorithms developed by NI (formerly National Instruments).
The 5G NR PHY-layer solution based on the Tektronix 6-Series B MSO offers significant advantages over traditional signal analysers, with wide signal analysis up to 2 GHz and low instrument noise for accurate EVM measurements. For high-frequency systems, such as FR2, the 5G NR analysis option is also available on the DPO70000SX which offers up to 70 GHz bandwidth. For engineers using real-time signal analysers, the 5G NR option is also available for the Tektronix RSA500 and RSA5000 Series. The software operates identically on oscilloscopes and signal analysers, eliminating the need to learn a new toolset.
