42 Chapter 4 Performance Verification Tests
Analog AC Voltage Performance Tests
Required Equipment The following list of equipment is required to test the analog AC performance
of the 3458A.
• Stable AC voltage source (Fluke 5700A or equivalent).
• Transfer Standard DMM (3458A Opt. 002 within 90 days of Cal.)
• Shielded test leads terminated with dual banana plugs (such as
Keysight 11000-60001).
Preliminary Steps 1. Make certain that the AC source is properly warmed up.
2. The 3458A requires a 4 hour warm up period. If this has not been
done, turn the instrument ON and allow it to warm up.
3. Execute the ACAL AC function on both the transfer standard DMM
and the UUT. This auto calibration will take approximately 1 minute
to complete.
4. If the instrument Self Test has not been run, make certain all inputs are
disconnected and execute the TEST function. The display must read
"SELF TEST PASSED".
5. Configure the transfer standard DMM as follows:
-- ACV
-- SETACV SYNC
-- ACBAND 10,2E6
-- RANGE10
-- RES .001
-- TRIG SGL
-- LFILTER ON
6. Configure the DMM under test as follows:
-- ACV
-- SETACV ANA
-- ACBAND 10,2E6
-- RANGE10
-- RES .01
-- TRIG SGL
-- LFILTER ON
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
