CEDGN_E6175A_LoadCard.tpa (8 Channel Load Card CEDGN Test Flow)
The testsplan supports testing of eight E6175A Load Cards.
User is required to set the variables to reflect the system under
test.
1 = present, 0 = not present
bLC8CH_1 = 1st E6175A
bLC8CH_2 = 2nd E6175A
bLC8CH_3 = 3rd E6175A
bLC8CH_4 = 4th E6175A
bLC8CH_5 = 5th E6175A
bLC8CH_6 = 6th E6175A
bLC8CH_7 = 7th E6175A
bLC8CH_8 = 8th E6175A
Device that user sets as not present will not be tested. The test
starts by performing:
Not Acceptable Combination Checking
• Checks user settings for any not acceptable combination. Stops
test and provide error message if not acceptable selection is found.
E6175A 8 Channel Load Card LC8CH_1 Tests
• Display instruction to Install load module E2240-67012 on LC8CH_1
Load Card.
• For LC8CH_1 on TC1, display instruction to install CEDGN Board
#4 on TC1 and Cable E6170-61607 from SLU Utility Connector to J2
of Board #4.
• For LC8CH_1 on other TC, display instruction to install CEDGN
Board #1 on TC1 and CEDGN Board #4 on appropriate TC. Install
Cable E6170-61607 from SLU Utility Connector to J2 of Board #4.
Install Cable E6170-61607 from J1 of Board #1 to J1 of Board #4.
• Setup DMM to perform 2W resistance measurement.
• Measure LC8CH_1 load card loopback path resistance from
CH1-CH5, CH2-CH6, CH3-CH7 and CH4-CH8 via Row1 and Row2.
• Measure LC8CH_1 load card sense resistor path:
CH1 & CH2 Current Sense, CH3 & CH4 Current Sense, CH5 & CH6
Current Sense, and CH7 & CH8 Current Sense via Row25 and
