Using A Spectrum Analyzer's Video-Filter Bandwidth

摘要

Spectrum-Analyzer users may have used one of their instrument's functions—the video-filter bandwidth (VFB)—without really understanding it. Most users may have only a vague idea what this function is for, or how to use it for best results. As a result, the VFB remains at its default setting which, while it may not be the worst setting, may also be less than optimum. By understanding the proper use of the VFB, most spectrum-analyzer measurements can be significantly improved.
