for MSO2000A-S and DS2000A-S models oscilloscopes, in the source interface,
press the corresponding menu softkey and then press the knob; the numeric
keyboard will pop-up on the screen and you can input the desired parameter value

Navigation Knob
This knob provides quick Adjust/Locate function
for numerical parameters with relatively large
settable range. Turn clockwise
(counterclockwise) to increase (reduce) the
value. The inner knob is used for fine adjustment
and the outer knob for coarse adjustment.
For example, this knob can be used to quickly locate the waveform frame (“Current
Frame” menu) to be played back in the waveform playback function. Similar menus
include trigger holdoff, pulse width setting, slope time etc.
