Verification and Adjustment Procedures-318/338 Service
NOTE
Over adjustment of the EVENTS LEVEL will cause a loss of the DD501 triggering
and oscilloscope display. If the adjustment range is not adequate, replace the 42
inch BNC cable, from DLY’D TRIG OUT to the #2 Pulse Generator’s +TRIG INPUT,
with a longer or shorter cable.
14. Set the 318 CLK and QUALIFIERS for Condition 1 in Table 5-9.
15. Press the 318 DATA key until the State Table is displayed.
16. Press the START key.
17. Check that the data acquired is equal to the Expected Data in Table 5-9.
19. Set the #1 pulse generator’s OUTPUT to NORM.
20. Adjust DD501 EVENTS LEVEL until the channel 2 waveform’s falling edge crosses channel 1’s falling edge at 0 V
(mid-screen). See Figure 5-30 (14 ns setup, 0 ns hold).
21. Change the 318 CLK and QUALIFIERS for Conditions 4, 5, and 6 in Table 5-9. Repeat steps 15 to 17 for each
Condition.
