function menu.
Select the memory location 3 by using multi‐purpose knob
Select DSO on the Disk selection
Press F4, a loading progress bar will be shown on the screen.
If loading is done, a white waveform should be displayed on the screen labelled Ref A.
If no waveform is stored at the selected memory location, you will see a system message
show "no data in the position"
Users can turn off the Ref A reference waveform by pressing OFF F3 button on the load
function menu.
Attention:
Loading the pre‐saved waveform into Ref B follows the same procedure as above.
If waveform is stored to the USB device, 200 available memory locations can be selected.
Please see "Set the Storage and Load System" for how to save a waveform to USB device.
2. Set the Horizontal System
The horizontal control knob can be used to change the horizontal scale (time base) and
trigger horizontal position (trigger position) in internal storage. The vertical midpoint in
screen horizontal direction is the time reference point of waveform. Changing of
horizontal scale can lead to expansion or shrink of waveforms relative to screen center.
When the horizontal position changes, the position relative to waveform trigger point
will be changed.
The horizontal system can be controlled by the following panel buttons/knobs.
