You’re designing a transmitter or receiver, or some part of one, maybe even the baseband chains. EVM (Error Vector Magnitude) or BER (Bit Error Ratio) may be the system specifications you must satisfy. This article has shown a quick method of obtaining relatively complex information about a design’s performance. This speeds troubleshooting and enables quick feedback during the investigation phase of a design. It is also possible to simulate specification-compliant EVM (as well as many other specifications) when precise information is needed.
