User Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
on the source signal.
To reduce random noise and aliased components in repetitive or single-shot events, set
the oscilloscope acquisition mode to average.
Term interpretation
Nyquist frequency: The highest frequency that any Real Time Digital Oscilloscope can
measure is exactly half of the sampling rate under the condition of no mistakes,which is
called Nyquist frequency. If under-sampling occurs when the frequency sampled is higher
than Nyquist frequency, "False Wave" phenomenon will appear. So pay more attention to
the relation between the frequency being sampled and measured.
NOTE：
In FFT mode, the following settings are prohibited:
1) Window set;
2) change source channel (in CH1 Setup or CH2 Setup menu);
3) XY Format in DISPLAY SET;
4) "SET 50%" (the triggering level at the vertical point of signal amplitude) in Trigger
setting;
5) Autoscale;
Measure 1 and Measure 2.

Application
VOLTS/DIV Knobs
1. The .VERTIVAL POSITION knob is used to adjust the vertical positions of the
wave forms of all Channels (including those resulted from the mathematical
operation).
The analytic resolution of this control knob changes with the vertical division.
2. The VOLTS/DIV knob is used to regulate the vertical resolution of the wave
forms of all channels (including those obtained from the mathematical
manipulation), which can determine the sensitivity of the vertical division with
the sequence of 1-2-5. The vertical sensitivity goes up when the knob is rotated
clockwise and goes down when the knob is rotated anticlockwise.
3. When the vertical position of the channel wave form is adjusted, the screen shows
the information concerning the vertical position at the lower left corner (see
Fig.5-13).
