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 3.
3. Set the range of the 3458A under test as specified in Table 3.
4. Set the AC source to the voltage level and frequency specified in
Table 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 3.
10. After all AC voltage tests have been performed, calculate and record
in the column provided, the difference between the transfer standard
DMM reading and the unit under test reading for each of the test
