Agilent 3070 Test 2340
Test DUT Power Supplies Ground Fault
Requires:
Pin Verification Fixture and DUT power supplies
This test must pass before the other DUT power supply tests can run.
Each of the four outputs1 on the DUT power supply are set to 10.0 volts with the current limit set to the minimum. Each DUT supply is measured while first one, then the other power lead is grounded. If any lead is shorted to ground, grounding the other lead will cause a current limit. If no leads are shorted to ground, no current limit will occur.
Subtest 0 measures the DUT power supply output 1 on the detector with the low lead grounded. Subtest 1 measures output 1 again, this time with the high lead grounded. Subtests 2 and 3 check DUT power supply output 2. Subtests 4 through 7 test DUT supply outputs 3 and 4.
