Front Panel Overview
This chapter describes the front panel controls of the Agilent U1600B 
series handheld digital oscilloscope series. The front panel keys are used 
for setting up and making scope and meter measurements. They provide 
access to the softkey menus for respective function and value setting 
selected by turning the rotary switch. These front panel keys lead you to 
the first layer of the function’s menu, where four softkeys located below 
the display are used to select the sub- menu of the function. With these 
four softkeys, you can access and alter the settings of the individual 
function. 
The rotary switch acts as an enter button to set as a selector to reposition 
a channel waveform. To adjust the value setting, turn rotary switch 
clockwise to increase or counter clockwise to decrease the value, and 
press the rotary switch to fix the value.
