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: Check if 99 ≤ R ≤ 101; if
yes, go to Block 17.
• Block 8: Check if 101 ≤ R ≤ 103; if
yes, go to Block 19.
• Block 9: Check if 104 ≤ R ≤ 106; if
yes, go to Block 21.
• Block 10: Check if 106 ≤ R ≤ 108; if
yes, go to Block 23.
• Block 11: Set digital I/O lines 1
through 4; output decimal 15 (binary
1111) to component handler.
• Block 12: Delay 1 ms. Controls
duration of digital bit patterns;
adjust as appropriate.
• Block 13: Set digital I/O lines 1
through 4; output decimal 0 (binary
0000) clear pattern to component
handler.
• Block 14: Notify block generates
event, which causes output of a
trigger pulse on digital I/O line 6.
• Block 15: Loop back to Block 2;
keep looping until all resistors have
been tested.
• Block 16: Go to Block 0 (go to Idle).
• Block 17: Set digital I/O lines 1
through 4; output decimal 1 (binary
0001) to component handler.
• Block 18: Go to Block 12.
• Block 19: Set digital I/O lines 1
through 4; output decimal 2 (binary
0010) to component handler.
• Block 20: Go to Block 12.
• Block 21: Set digital I/O lines 1
through 4; output decimal 3 (binary
0011) to component handler.
• Block 22: Go to Block 12.
• Block 23: Set digital I/O lines 1
through 4; output decimal 4 (binary
0100) to component handler.
•
Block 24: Go to Block 12.
