Performance Verification
19. Turn Multipurp
ose a knob and select the appropriate channel, such as D0.
20. With the Fine front-panel button turned off, turn Multipurpose b knob and
set the value t
o 4.00 V (+4.0 V/div). To remove the menu from the display,
push the front-panel Menu Off button.
21. Set the DC vo
ltage source (Vs) to +4.4 V. Wait 3 seconds. Check the logic
level of the corresponding digital channel in the display.
If the chann
el is a static logic level low, change the DC voltage source Vs to
+4.5 V.
22. Decrement
Vs by -10 mV. Wait 3 seconds and check the logic level of the
corresponding digital channel in the display. If the channel is at a static logic
level low, record the Vs value as V
s+
in the 4 V row of the test record.
If the channel is a logic level 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.
23. Push the front-panel Trigger Menu button.
24. Push the Slope lower-bezel button to change the slope to Rising.
25. Set th
e DC voltage source (Vs) to +3.6 V. Wait 3 seconds. Check the logic
level of the corresponding digital channel in the display.
If th
e channel is a static logic level high, change the DC voltage source Vs to
+3.5 V.
26. Inc
rement Vs by +10 mV. Wait 3 seconds and check the logic level of the
corresponding digital channel in the display. If the channel is at a static logic
level high, record the Vs value as in the 4 V row of the test record.
If the channel is a logic level 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.
27. Find the average, 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 passes the test.
28. Repeat the procedure starting with step 11 for each remaining digital channel,
D1 through D15.
This completes the performance verification procedure.
