Chapter 4 Main Feature Description
This   chapter   provides   some   general   information   that   you   need   to   learn   before   using   an 
oscilloscope. It contains:
1. Oscilloscope setup
2. Trigger
3. Data acquisition
4. Waveform scaling and positioning
5. Waveform measurement 
4.1 Oscilloscope Setup
While operating the oscilloscope, you may often use three features: Autoset, saving a setup and 
recalling a setup. Hereinafter they are introduced one by one. 
Autoset: This function can be used to adjust the horizontal and vertical scales of the 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. To 
view the default settings, refer to Section 5.6.3. 
4.2 Trigger
The trigger determines when the oscilloscope begins to acquire data and display a waveform. 
Once a trigger is properly set up, the oscilloscope can convert unstable displays or blank screens
