Measuring a Low−Level Signal
Decreasing the Resolution Bandwidth
Figure 3-3 Default resolution bandwidth
6 Decrease the RBW. • Press BW, 47, kHz. The low-level signal appears more
clearly because the noise level is
reduced. See Figure 3-4.

A “#” mark appears next to the Res BW annotation in the lower left corner of the screen, indicating that the
resolution bandwidth is uncoupled.
