No matter the signal type, whether it be simple CW signals or complex digitally-modulated signals, every signal has some amount of distortion.
Signal distortion is important to characterise in your system because it can result in energy at unintended frequencies. However, being able to clearly see low level signals is difficult to do, especially if they are buried beneath the noise floor of your signal analyser. There are several ways to improve the dynamic range of a signal analyser.
Today Keysight will discuss how you can optimise your signal analyser’s dynamic range so that you can more easily see low level signals.
