ACQUISITION
Opens and closes the "Acquisition" tab in the "Horizontal" dialog box, where you
can define the acquisition processing (decimation and arithmetic).
RESOLUTION / RECORD LENGTH
The rotary knob changes the resolution or the record length. Press the knob to
toggle the setting. The controlled parameter and its value are shown in the input
box in the upper left corner of the screen.
For resolution, turn clockwise to increase the resolution: the time between two
acquisition points gets shorter. Record length and sample rate increase while the
acquisition time remains constant.
For record length, turn clockwise to increase the record length, and the resolution
increases too - the time between to acquisition points gets shorter.
POSITION / REF POINT
The rotary knob changes the horizontal position of the waveform or the position of
the reference point on the screen.
Press the knob to toggle the setting. The controlled parameter and its value are
shown in the input box in the upper left 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.
