Improvement of Oscilloscope Based RF Measurements by Statistical Averaging Techniques
Paper i proceeding, 2006
This paper demonstrates a method for accurate characterization of modulated microwave signals using a digital storage oscilloscope (DSO). Repeated measurements of the modulated signal are used with statistical averaging techniques to significantly improve the dynamic range. The performance of the method is evaluated by residual EVM and RF spectrum measurements. AM/AM measurements using two DSO channels are used to demonstrate the ability to perform synchronous input/output PA characterization.
