Demystifying 5G – RF sampling ADCs: how to verify modulation performance?

Latest high speed data converters simplify new 5G NR designs with their capability of direct synthesis and direct sampling at RF frequencies. The video demonstrates how to verify the modulation performance of a high speed ADC on the digital side. The example shows an error vector magnitude (EVM) measurement on a two-channel 5.2 Gsample analog to digital converter from Texas Instruments using the R&S®SMW200A vector signal generator, the R&S®SMA100B RF and microwave analog signal generator and the R&S®VSE vector signal analysis software from Rohde & Schwarz.

The demystifying 5G video series discusses main topics related to 5G including new technology components, procedures and testing challenges.
