Digital Storage Oscilloscope 11
oscilloscope automatically and set the trigger coupling, type, position, slope, level and
mode, etc., to acquire a stable waveform display.
Saving a Setup: By default, the oscilloscope will save the setup each time before
being closed, and automatically recall the setup once being turned on. (Note: If you
modify the setup, please wait for more than 5 seconds before turning off the
oscilloscope to ensure the proper storage of new settings.) You can save 10 settings
permanently in the oscilloscope and reset them as necessary.
Recalling a Setup: The oscilloscope can recall any of your saved setups or the default
factory setup.
Default Setup: The oscilloscope is preset for normal operations when it is shipped
from the factory. This is the default setup. You may recall this setup at any time for your
requirements.
2.6 Horizontal Controls
Use the horizontal controls to change the horizontal scale and position of waveforms.
The horizontal position readout shows the time represented by the center of the screen,
using the trigger time as zero. When you change the horizontal scale, the waveform will
expand or contract to the screen center. The readout near the upper right of the screen
shows the current horizontal position in second. M represents ‘Main Time Base’, and W
indicates ‘Window Time Base’. The oscilloscope also has an arrow icon at the top of
the graticule to indicate the horizontal position.
1. Horizontal Position Knob: Used to control the trigger position against the screen
center. Push this button to reset the trigger point back to the screen center.
AN: Used to set the horizontal position as zero.
