Acquiring Waveforms
CSA8000B & TDS8000B User Manual 3- 15
The vertical scale and position controls do not affect the vertical acquisition
window, rather they adjust the display system to display the waveform as
follows:
H The vertical scale (per division) setting determines the portion of the vertical
acquisition window that appears in the graticule, allowing you to scale it to
contain all of the window or only part. Figure 3--2 shows two vertical
acquisition windows that contain the entire waveform, but only one window
contains the entire waveform in the graticule on screen.
a. Volts/Div setting determines the size of the display graticule within the vertical
acquisition window (scale set to 50 mv/div.)
+0.25 volt
--0.25 volt
b. Vertical position can change location of display graticule within
±5 divisions
(position set to --4 divisions)
