AWG510 & AWG520 Service Manual
b. Generate an event signal: Close the SW1 of the ground closure to
generate an event signal on the EVENT IN connector pin 0.
c. Confirm the waveform on the oscilloscope: Confirm that the oscilloscope
displays the waveform as shown in Figure 4–23 and that the waveform
amplitude is almost as half as that in Figure 4–22.
Figure 4-23: Waveform output when the SW1 is closed
d. Degenerate the event signal: Open the SW1 of the ground closure to
degenerate the event signal.
e. Confirm the waveform on the oscilloscope: Confirm that the oscilloscope
displays back the waveform in Figure 4–22.
6. Check the EVENT IN connector pin 1 input:
a. Generate an event signal: Close the SW2 of the ground closure to
generate an event signal on the EVENT IN connector pin 1.
b. Confirm the waveform on the oscilloscope: Confirm that the oscilloscope
displays the waveform as shown in Figure 4–24.
