2.2.9 Measuring low level signals
Reducing the noise level allows you to measure low-level signals. The noise level can be reduced by nar-
rowing the resolution bandwidth. If the video bandwidth is set or the averaging function is used, you can
observe the signals that are lost in the noise. Additionally, using the built-in pre-amplifier allows you to
measure still lower level signals.
Setup
1. Connect the signal generator as shown in Figure 2-27.
