2. Verify that all channels operate: Do the following substeps — test CH 1
first, skipping substep a and b since CH 1 is already set up for verification
and as the trigger source from step 1.
a. Select an unverified channel:
H Press WAVEFORM OFF to remove the channel just verified from
display.
H Press the front-panel button that corresponds to the channel you are
to verify.
H Move the probe to the channel you selected.
b. Match the trigger source to the channel selected:
H Press TRIGGER MENU.
H Press the main-menu button Source.
H Press the side-menu button that corresponds to the channel selected,
Ch2, Ch3, or Ch4. (Some TDS models use Ax1 and Ax2 instead of
Ch3 and Ch4).
c. Set up the selected channel:
H Set the vertical SCALE to 200 mV.
H Set the horizontal SCALE to 200 ms. Press CLEAR MENU to
remove any menu that may be on the screen.
H Press SET LEVEL TO 50%.
d. Verify that the channel is operational: Confirm that the following
statements are true.
H The vertical scale readout for the channel under test shows a setting
of 200 mV, and a square-wave probe-compensation signal about
2.5 divisions in amplitude is on-screen. See Figure 1–1 on page 1–3
to locate the readout.
H The vertical POSITION knob moves the signal up and down the
screen when rotated.
H Turning the vertical SCALE knob counterclockwise decreases the
amplitude of the waveform on-screen, turning the knob clockwise
increases the amplitude, and returning the knob to 200 mV returns
the amplitude to about 2.5 divisions.
