 " on P34.
 Use the default dB scale for details of multiple frequencies, even if they
have very different amplitudes. Use the Vrms scale to compare
frequencies.
 DC component or offset can cause incorrect magnitude values of FFT
waveform. To minimize the DC component, choose AC Coupling on the
source signal.
 To reduce random noise and aliased components in repetitive or
single-shot events, set the oscilloscope acquisition mode to average.
What is Nyquist frequency?
The Nyquist frequency is the highest frequency that any real-time digitizing
oscilloscope can acquire without aliasing. This frequency is half of the sample rate.
Frequencies above the Nyquist frequency will be under sampled, which causes
aliasing. So pay more attention to the relation between the frequency being sampled
and measured.

Use VERTICAL POSITION and VOLTS/DIV Knobs

1. The VERTIVAL POSITION knob is used to adjust the vertical positions of the
captured waveforms. When turning this knob, the information of vertical position
will be displayed on the bottom left of the waveform display area; it will disappear
after stopping turning the knob.
The analytic resolution of this control knob changes with the vertical division.
The VOLTS/DIV knob is used to regulate the vertical resolution of the
2.
captured waveforms. The sensitivity of the vertical division steps as 1-2-5.
The information of voltage division is displayed in channel window on the
bottom left of the screen.
