Some of the shortcomings of traditional interference analysis are examined. Traditional swept-tuned and FFT spectrum analyzers can effectively detect a relatively constant signal. However, these analyzers are less effective when measuring random bursty signals, narrow pulses, or signals with duration based on network traffic conditions. Detecting such challenging signals can be achieved by utilizing RTSA, which can detect transient signals, dynamic signals, and RF pulses within a specific bandwidth.
Several important RTSA performance indicators are mentioned, such as real-time bandwidth, minimum signal duration for 100% probability of intercept (POI), and dynamic range. Moreover, two types of challenging interference in the field—co-channel and uplink interference—are touched upon, along with an explanation of how RTSA can help detect both types. The application note also states that component failures lead to many instances of interference, with further discussion of how component-based problems can be prevented. Lastly, the document concludes with a description of Keysight’s FieldFox handheld analyzers.
