TDS 520A, 524A, 540A, & 544A Performance Verification
b.
Initialize the oscilloscope:
Press save/recall SETUP.
Press the main-menu button Recall Factory Setup.
Press the side-menu button OK Confirm Factory Init.
2.
Verify that all input channels operate:
Do the following substeps
—
test
CH 1 first,
skipping substep
a since CH 1 is already set up for verification
from step 1.
a.
Select an unverified channel:
Press WAVEFORM OFF to remove from display the channel just
verified.
Press the front-panel button that corresponds to the channel you
are to verify.
Move the probe to the channel you selected.
b.
Set up the selected channel:
Press AUTOSET to obtain a viewable, triggered display in the
selected channel.
Set the horizontal SCALE to 200 s. Press CLEAR MENU to
remove any menu that may be on the screen.
c.
Verify that the channel is operational:
Confirm that the following
statements are true.
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.)
The vertical POSITION knob moves the signal up and down the
screen when rotated.
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.
d.
Verify that the channel acquires in all acquisition modes:
Press
SHIFT; then press ACQUIRE MENU. Use the side menu to select, in
turn, each of the five hardware acquire modes and confirm that the
following statements are true. Refer to the icons at the left of each
statement as you confirm those statements.
Sample mode displays an actively acquiring waveform on-
screen. (Note that there is noise present on the peaks of the
square wave.)
Peak Detect mode displays an actively acquiring waveform
on-screen with the noise present in Sample mode “peak de-
tected.”
