2.2.9 Dynamic Range
The dynamic range can be increased by reducing the noise level, which is accomplished by narrowing the
resolution bandwidth. The noise level can be further reduced by setting the video bandwidth (VBW) to
approximately 1/10 of the resolution bandwidth (RBW).
Setup
1. Connect the signal generator as shown in Figure 2-35.
