Position Softkey
Position Softkey
The position softkey is the fourth softkey. Selecting position assigns
position as the active function. You can use the position knob to change the
position setting at any time, even if you are in a different menu or when
position is not the active function. When position is the active function, you
can use either the position knob or the entry knob to change the position
setting of the selected channel.
position moves the trace vertically up or down similar to the vertical position
adjustment on an analog oscilloscope. However, because digital oscilloscopes
have a true dc offset at the front end, they provide a much wider offset range.
When the Show key is pressed, the position voltage is shown at the right of
the waveform display. The position value is the voltage level at the vertical
center of the screen.
