Clear any existing trigger model commands
from the instrument.
Set up the trigger model:
• Block 1: Clear default buffer 1.
• Block 2: Set up a wait block to wait for
digital line 5.
• Block 3: Turn the source output on.
• Bock 4: Set a constant delay of .001
s.
• Block 5: Make a measurement and
store it in default buffer 1.
• Block 6: Turn the output off.
• Block 7: Set up the constant limits to
perform the first test.
• Block 8: If block 7 fails, drive the
digital I/O lines high.
• Blocks 9, 12, 15, and 18: Branch to
block 20.
• Block 10: Set up the constant limits to
perform the second test.
• Block 11: If block 10 fails, drive line 1
high.
• Block 13: Set up the constant limits to
perform the third test.
• Block 14: If block 13 fails, drive line 2
high.
• Block 16: Set up the constant limits to
perform the fourth test.
• Block 17: If block 10 fails, drive lines 1
and 2 high.
• Block 19: If block 10 fails, drive line 3
high.
• Block 20: Delay for 1 ms
• Block 21: Set all digital lines low.
• Block 22: Send out a notify event to
indicate that the test has ended.
•
Block 23: Return to block 2 23 times.
