Horizontal Controls
The keys and rotary knobs in the Horizontal functional block adjust the acquisition
settings and horizontal parameters. These settings are effective for all channel
waveforms.
[Position]
The rotary knob changes the horizontal position of the waveform or the position of
the reference point on the screen.
You can select if the knob changes the position or the reference point in "Menu" >
"Settings" > "Frontpanel" > "Knobs" dialog. To set the value to zero, press the
knob. The current value is shown in the input box in the upper right corner of the
screen.
"Horizontal position" defines the time distance of the reference point from the zero
point of the diagram. Turn clockwise to move the waveform to the right.
"Reference point" defines the position of the reference point on the screen. Turn
clockwise to move it to the right. The reference point marks the rescaling center
of the time scale. It is indicated by a gray triangle outline at the top of the dia-
gram. If you modify the time scale, the reference point remains fixed on the
screen, and the scale is stretched or compressed to both sides of the reference
point.
[Scale]
The rotary knob adjusts the time scale for all signals. The time scale is also
known as timebase.
Turn clockwise to stretch the waveforms. Doing so, the scale value
time/div
decreases.
Press the knob to toggle between coarse and fine scale adjustment.
[Zoom]
Displays a zoom diagram for the active diagram. The key is illuminated if at least
one zoom is active. If you press the key while the zoom function is on, the "Zoom"
dialog box opens, where you can configure several zoom areas for detailed signal
observation.
