RES / REC LEN
Opens and closes the "Resolution" tab in the "Horizontal" dialog box, where you can
set the resolution and the record length.
HORIZONTAL
Opens and closes the "Time Base" tab in the "Horizontal" dialog box, where you can:
●
Adjust the time scale, and acquisition time
●
Adjust the horizontal position, and reference point
●
Enable the roll mode
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 acquisi-
tion points gets shorter; and record length and sample rate increase while the acquisi-
tion time remains constant.
For record length, turn clockwise to increase the record length, and the resolution
increases - the time between to acquisition points gets shorter.
POSITION / REF POINT
The rotary knob changes the horizontal position of the waveform or the screen position
of the reference point. 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.
The reference point marks the rescaling center of the time scale. It is indicated by a
gray triangle outline at the top of the diagram. If you modify the time scale, the refer-
ence point remains fixed on the screen, and the scale is stretched or compressed to
both sides of the reference point.
"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 clock-
wise to move it to the right.
SCALE
The rotary knob adjusts the time scale for all signals. The time scale is also known as
time base.
Turn clockwise to stretch the waveforms. Doing so, the scale value time/div decreases.
3.1.4 TRIGGER Controls
The keys and knob in the TRIGGER functional block adjust the trigger and start or stop
acquisition.
