Set the instrument so that the questionable limit channel status event
register's bits 1 and 2 are set to 1 only when the questionable limit channel
status register's bits 1 and 2 are changed from 0 to 1 (positive transition).
Line 3240
Enables the questionable limit channel status event register's bits 1 and 2.
Procedure: Display_Update (lines 3280 to 3620).
Line 3300
Updates the display on the LCD screen once.
Lines 3320 to 3380
When trace 1's limit test result is Fail (Test_Tr1 = 2), these lines display
Tx(S13) "Limit test result: Fail" on the user form (object name:
frmDupRes) against a red background. On the other hand, when trace 1's
limit test result is Pass (Test_Tr1 ¼ 2), they display Tx(S13) "Limit test
result: Pass" on the user form (object name: frmDupRes) against a blue
background.
Lines 3400 to 3460
When trace 2's limit test result is Fail (Test_Tr2 = 4), these lines display
Rx(S21) "Limit test result: Fail" on the user form (object name:
frmDupRes) against a red background. On the other hand, when trace 1's
limit test result is Pass (Test_Tr2 ≠ 4), they display Rx(S21) "Limit test
result: Pass" on the user form (object name: frmDupRes) against a blue
background.
Lines 3480 to 3540
When channel 1's limit test result is Fail (Test_Ch1 = 2), these lines
display "Overall limit test result: Fail" on the user form (object name:
frmDupRes) against a red background. On the other hand, when channel
1's limit test result is Pass (Test_Ch1 ≠ 2), they display "Overall limit test
result: Pass" on the user form (object name: frmDupRes) against a blue
background.
Lines 3560 to 3600
Display the analysis results for traces 1 and 2 (insertion loss and band-
pass ripple) as Tx(S13) and Rx(S21), respectively, on the user form
(object name: frmDupRes).
