Unlike other oscilloscopes or digital 
multimeters, the GDS-200 and GDS-300 Series 
have no physical hardware keys, therefore 
operation is completely controlled using the 
capacitive touch screen. Using a capacitive 
touch screen is a new interface paradigm for 
DSOs; the gestures and general user interface is 
easier to use and more intuitive than 
traditional DSO interfaces. Before you begin to 
use these instruments, we highly recommend 
you take a few moments to get to know the 
basic gestures and interface conventions. 
There are a few basic gestures that can be used 
to operate the GDS-200/GDS-300. When asked 
to perform a gesture throughout the user 
manual, you can refer to the gestures below.
