The Keysight/Agilent/HP 3563A Signal Analyzer is excellent for analysis of low frequency signals such as audio and mechanical systems including structural dynamics and machinery vibration.
Measurements at the push of a button, capturing rare events with event-based actions and simple script programming with the SCPI recorder – setting up complex measurements in no time is the strength of the R&S®FSV3000 signal and spectrum analyzer. Its other major advantage is its fast measurement speed, allowing high throughput in production applications.
