1 = present, 0 = not present
bLC48CH_1 = 1st N9379A
bLC48CH_2 = 2nd N9379A
bLC48CH_3 = 3rd N9379A
bLC48CH_4 = 4th N9379A
NOTE: All N9379A need to be installed with load modules
E6170-66520
Device that user sets as not present will not be tested. The test
starts by performing:
N9379A 48 Channel Load Card LC48CH_1 on TC1 (CH1 until CH24)
Tests
• Display instruction to install CEDGN Board #4 on TC1.
• Setup DMM to perform 2W resistance measurement.
• Measure LC48CH_1 load card loopback path resistance from
CH1-Com1 via Load1.1/Load1.2 until CH12-Com12 via
Load12.1/Load12.2 using Row 1 and Row8.
CH13-Com13 via Load13.1/Load13.2 until CH24-Com24 via
Load24.1/Load24.2 using Row 2 and Row7.
N9379A 48 Channel Load Card LC48CH_1 on TC2 (CH25 until

Board #4 on appropriate TC2. Install Cable E6170-61607 from J1 of
Board #1 to J1 of Board #4.
• Setup DMM to perform 2W resistance measurement.
• Measure LC48CH_1 load card loopback path resistance from
CH25-Com25 via Load25.1/Load25.2 until CH36-Com36 via
Load36.1/Load36.2 using Row 1 and Row8.
CH37-Com37 via Load37.1/Load37.2 until CH48-Com48 via
