Front-Panel Overview
Entry/Measure
Entry Knob
The entry knob changes values within each function. It increments,
decrements, or toggles the selection in the active field or function. The
current selection is displayed in full-bright in the softkey menu area.
Fine Key
The Fine key changes the increment and decrement sequence. Instead of
sequencing in the normal sequence, the values increment or decrement in
more precise values. You can use this feature when the normal sequence is
too coarse for precision measurements or settings. When the oscilloscope is
operating in the fine mode, the word "fine" is displayed in the lower right
corner of the display, and the LED next to the fine key is illuminated.
Blue Shift Key
The blue shift key allows you to access the functions that are written in blue
above the other keys on the front panel. When you press the blue shift key,
the message "select shift function" is displayed, and the LED next to the blue
shift key is iluminated.
