13.  You may click 

 or 

 to increase or decrease the delay time. 

14.  The oscilloscope offers three types of horizontal mode functions, which are 

Main Mode

Roll 

Mode

, and 

XY Mode

. You may select the horizontal mode by clicking the drop-down list 

under 

Mode

 
 

Measurement and Cursor Controls 
 

1.  The 

Measurements & Cursors

 button is located on the toolbar of the soft front panel. 

2.  Click 

 to activate the automated measurement and cursor system. 

This will display the window as shown below:

3.  The oscilloscope provides three types of settings for marker property, which are 

Auto

Manual

, and 

Off

4. 

Auto

 marker automatically places the cursors on the graph based on the selected 

measurements. 

5. 

Manual

 marker allows the cursors to be placed manually on the graph for customized 

measurements. This will enable the 

Cursors

 panel. 

6. 

Off

 will disable the graph markers from the graph display. 

7.  If the 

Manual

 marker is selected, the 

Cursors

 control will be enabled. This is shown in Figure
