Horizontal Position and Horizontal Scale.
1. Horizontal Position knob: this knob is used to adjust the horizontal positions of all
channels (include those obtained from the mathematical manipulation), the analytic
resolution of which changes with the time base.
2. Horizontal Scale knob: it is used to set the horizontal scale factor for setting the main
time base or the window.
3. Horizontal HOR button: push it to switch between the normal mode and the wave zoom
mode. For more detailed operations, see the introductions below.
Zoom the Waveform
Push the Horizontal HOR button to enter wave zoom mode. The top half of the display shows
the Main window and the bottom half displays the Zoom window. The Zoom window is a
magnified portion of the Main window.
In normal mode, the Horizontal Position and Horizontal Scale knobs are used to adjust the
horizontal position and time base of the Main window.
In wave zoom mode, the Horizontal Position and Horizontal Scale knobs are used to adjust
the horizontal position and time base of the Zoom window.
How to Set the Trigger System
Trigger determines when DSO starts to acquire data and display waveform. Once trigger is
set correctly, it can convert the unstable display to meaningful waveform.
When DSO starts to acquire data, it will collect enough data to draw waveform on left of trigger
point. DSO continues to acquire data while waiting for trigger condition to occur. Once it
detects a trigger it will acquire enough data continuously to draw the waveform on right of
trigger point.
Trigger control area consists of 1 knob and 2 menu buttons.
Trigger Level: The knob that set the trigger level; push the knob and the level will be set as
the vertical mid point values of the amplitude of the trigger signal.
