Spectrum Analyzer Basics: Bandwidth

PublishTime：2021-12-28

●Modern spectrum analyzers offer flexible measurement capabilities. Select an analyzer that provides an adjustable RBW/VBW (lower is better), lower phase noise than the signal you are testing. Adjusting the RBW can provide lower noise floor and fine frequency resolution, but the sweep time will increase dramatically. For noisy signals, you can lower the VBW to help smooth the trace and make signal identification easier, but this will also increase sweep time. If you are performing EMI measurements, a 6dB sharper filter option is required to increase peak detection accuracy.
