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 menu, select 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
Using the Acquisition Controls on page 3--28 for more information):
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.
8. Test all channels: Repeat steps 2 through 7 until all four input channels are
verified.
9. Remove the test hookup: Disconnect the equipment from the channel input
and the probe compensation output.
