c. Select channel
D0.
d. Push the Fine front-panel button to turn off the fine adjustment.
e. Set the value near 4.00 V (4 V/div).
f. Push the Fine buttontoturnthefine adjustment on again.
g. Set the value to exactly 4.00 V (4 V/div).
13. Set the DC voltage source (Vs) to +4.4 V. Wait 3 seconds. Check the logic
levelofthechannelD0signaldisplay.
14. Decrement Vs by -10 mV. Wait 3 seconds and check the logic level of the
channel D 0 signal display. If it is a static logic low, record the Vs value as
V
s+
in the 4 V row of the test record.
If the signal level is a logic high or is alternating between high and low, repeat
this step (decrement Vs by 10 mV, wait 3 seconds, and check for a static logic
low) until a value for V
s+
is found.
15. Push the front-panel Trigger Menu button.
16. Click the lower-bezel Slope button to change the slope to Rising.
17. Set the DC voltage source (Vs) to +3.6 V. Wait 3 seconds. Check the logic
levelofthechannelD0signaldisplay.
If the signal level is a static logic high, change the DC voltage source Vs to
+3.5 V.
18. Increment Vs by +10 mV. Wait 3 seconds and check the logic level of the
channel D 0 signal display. If it is a static logic high, record the Vs value as
V
s-
in the 4 V row of the test record.
If the signal level is a logic low or is alternating between high and low, repeat
this step (increment Vs by 10 mV, wait 3 seconds, and check for a static logic
high) until a value for V
s-
is found.
19. Find the average using this formula: V
sAvg
=(V
s-
+V
s+
)/2. Record the average
as the test result in the test record.
Compare the test result to the limits. If the result is between the limits, the
channel pa sses t he test.
20. Repeat the procedure for all remaining digital channels as follows:
a. Push the D15–D0 button.
b. Move the DC voltage source connection, including the ground lead, to the
next digital channel to be tested.
c. Starting from step 3, repeat the procedure until all 16 d igital channels
have been tested.
