H
The front-panel vertical POSITION knob (for the channel you are
testing) moves the signal up and down the screen when rotated.
H
Turning the vertical
SCALE
knob counterclockwise (for the channel you
are testing) decreases the amplitude of the waveform on-screen, turning
the knob clockwise increases the amplitude, and returning the knob to
the original scale setting returns the amplitude to that shown in
Table 1--3 for that scale setting.
7. Verify that the channel acquires in all acquisition modes: From the
Horiz/Acq

Horizontal/Acquisition Setup . . .
. Click the
Acquisition tab in the control window that displays. Click each of the
acquisition modes and confirm that the following statements are true (see

H
Sample mode displays an actively acquiring waveform on-screen. (Note
that there is a small amount of noise present on the square wave).
H
Peak Detect mode displays an actively acquiring waveform on-screen
with the noise present in Sample mode “peak detected.”
H
Hi Res mode displays an actively acquiring waveform on-screen with the
noise that was present in Sample mode reduced.
H
Average mode displays an actively acquiring waveform on-screen with
the noise reduced.
H
Envelope mode displays an actively acquiring waveform on-screen with
the noise displayed.
H
Waveform Database mode displays an actively acquiring waveform
on-screen that is the accumulation of several acquisitions.
