Capturing Pulsed/Intermittent Signals with Frequency Swept, Frequency Stepped, and Time Domain Scan Methodologies

Overview: Pulsed and/or intermittent signals are difficult to detect and even more difficult to properly characterize the amplitude across frequency. The ability to properly capture and characterize these intermittent signals is an important capability to the EMC engineer. There are several methods to perform the task and each has its own strengths and weaknesses. Thorough understanding of the method of measurement is necessary. During this technical session, we will compare three methodologies, namely Frequency Swept, Frequency Stepped and Time Domain Scan. We will demonstrate the details of each for a pulsed signal stimulus and provide insight for best measurement techniques for each method.
