5. Verify that both output can be varied to the specifications given in Table 11-1:
6. Press , , use the RPG control to set the Hi-level
to its maximum (1.5 V).
7. Press , use the RPG control to set the clock amplitude to its
maximum level (2 V).
8. Select only the Clock scope channel to be ON.
9. Press Autoscale on the scope and select the DELTA V markers ON.
10.Set Marker 2 to the trough of the signal and Marker 1 to the peak of the signal. Read
Marker 1 as the “High Output level” and ∆V as the “Maximum amplitude”. Enter these
values in the Performance Test Record.
11.Press , use the RPG control to set the Hi-level to
its minimum (−3V).
12.Press , use the RPG control to set the clock amplitude to its
minimum level (500 mV).
13.Set Marker 2 to the trough of the signal and Marker 1 to the peak of the signal. Read
Marker 1 as the “Low Output level” and ∆V as the “Minimum amplitude”. Enter these
values in the Performance Test Record.
14.Repeat 1 to 13 with only the CLOCK scope channel ON, to obtain CLOCK amplitude
and Hi-level readings. These should also be entered on the Performance Test Record.
15.Set both the Clock and Clock channels to ON. Press , to be
OFF.
16.Repeat steps 1 to 7 for both channels, ensuring that each signal is independently
adjustable.
17.Set the CLOCK and CLOCK outputs NOT to track each other as follows: Select
then set to
18.Verify that both outputs can be varied independently to the specifications given in
Table 11-1.
