BASIC CONTROLS
Front Panel Controls
The control buttons of the instrument's front panel are logically grouped into analog and special
functional areas. Analog functions are included in the Horizontal, Trigger, and Vertical groups of
control buttons and knobs.
Sometimes you may want to change a value without using the numeric keypad. In that case, simply
touch once inside the data entry field in the scope dialog area (the field will be highlighted in yellow),
then use the Adjust group of buttons and single knob to dial in values into the selected field.
By default, the control knob makes coarse adjustments (that is, digits to the left of the decimal point).
Press the Fine button to adjust digits to the right of the decimal point. To enter exact values, you
can also display a keypad by touching twice inside the data entry field. Then use the keypad to type
in the value. The Select button steps through a dialog from one control to the next.
Example Data Entry Field
Note: You can set the granularity (delta) of the coarse adjustment in two ways:
• By pressing and holding the Fine front panel button while turning the Adjust knob. In this case you can read the changing
delta in the data entry field that is selected:
• By double-tapping inside the data entry field, then touching the Advanced checkbox in the pop-up numeric keypad. The
keypad presents Coarse delta up/down buttons to set the delta: . In the pop-up keypad, be sure
to leave the Fine checkbox unchecked to adjust the coarse delta.
