AC voltage test procedure
The following is a step-by-step procedure for all test points in the AC performance
verification section. The procedure requires alternately connecting the transfer
standard DMM and then the 3458A under test to the AC source. Because of this
and because the accuracy of AC coupled measurements does not suffer due to
small thermal induced offsets, the test connection can be made using shielded
test leads terminated with dual banana plugs. Refer to the general test procedure
for test connections.
1 Connect the AC voltage source to the transfer standard DMM.
2 Set the range of the transfer standard DMM as specified in Table 4-3.
3 Set the range of the 3458A under test as specified in Table 4-3.
4 Set the AC source to the voltage level and frequency specified in Table 4-3
5 Execute Trig SGL and read the output of the AC source as measured with the
transfer standard DMM and record this reading in the “Transfer standard
reading” column of the AC VOLTAGE TESTS Test Card.
6 Remove the connection from the transfer standard DMM to the AC source.
7 Connect the 3458A under test to the AC source.
8 Execute Trig SGL and read the value as measured with the 3458A under test
and record this value in the “Unit under test reading” column of the AC
VOLTAGE TESTS Test Card.
9 Repeat steps 1 through 8 for each of the remaining AC voltage test points as
specified in Table 4-3.
