2.2.7
Dynamic Range
The dynamic range can be increased by reducing the noise level, which is accomplished by making the
resolution bandwidth narrower. The noise level can be further reduced by setting the video bandwidth
(VBW) to approximately 1/10 of the resolution bandwidth (RBW). In addition, noise level can be reduced
in a short time using the average function.
Setup
1.
Connect the signal generator as shown in Figure 2-41.
