Note: The signal’s amplitude
is acquired on approximately
six divisions, corresponding to
5/8 = 192 levels or 7.32 bits of
quantification used.

The screen will display:
Use to adjust the channel input sensitivity and
have the signal fill all eight divisions of the screen.
And to even more finely adjust the sensitivity, press
7LSV
: Changing the sensitivity using the VAR button will
give a non-rounded gain — for example, 12.8 mV/DIV.
Determining the amplitude of the signal by reading visually
from the screen can be difficult. To avoid reading errors, use
CURSORS (see
Accurate Measuring with Cursors , page
3–16).
