Horizontal Position - Tenma 72-2650 User Manual

7. Press REF B and select the second signal source for the math function repeating
step 3
Note: To measure and observe such waveforms you can compare the current waveform
with the reference waveform for analysis.
8. Press REF to display the reference waveform menu. See following table:

• To store to a selected location choose between 1 and 10. To use external USB, plug
in the U disk and press F2 to select the USB memory.
• To save a waveform press SAVE menu.
Horizontal system setup
• The horizontal rotary control is used to change the graticule (time
base) and trigger the horizontal position of the memory (triggering
position).
• The vertical centre point above the horizontal orientation of the
screen is the time reference point of the waveform. Changing the
graticule will cause the waveform to increase or decrease in size
relative to screen centre. When the horizontal position changes, the
position in respect to the waveform triggering point is also changed.

Horizontal position

• Adjust the horizontal positions of the channel waveforms (including
math waveforms). Resolution of this control changes with the time
base.
Horizontal scaling
• Adjusting the main time base i.e. sec/div. When time base extension
is on you can use the horizontal scaling control to change the delay
scanning time base and change the window width.
