(3) Adjust spectrum analyzer controls to display fundamental frequency (100 kHz)
and at least four harmonics. All harmonics will be at least 45 dB below fundamental.
(4) Repeat technique of (2) and (3) above for frequencies listed in table 4. Spectrum
analyzer will indicate within limits specified.

a. Performance Check
(1) Execute multimeter ACAL AC command by pressing keys as listed in (a)
through (c) below:
(a) MENU Auto Cal.
(b) FUNCTION/RANGE Menu Scroll ⇓ until ACAL AC is displayed.
(c) NUMERIC/USER 3458 then Enter.
NOTE
ACAL AC takes approximately 1 minute to complete.
(2) Connect calibrator OUTPUT to multimeter INPUT HI and LO terminals.
(3) Set calibrator for a 1.00574 V, 100 kHz output.
(4) Record multimeter reading as indication #1.
(5) Set calibrator for a 0.99423 V, 100 kHz output.
(6) Record multimeter reading as indication #2.
(7) Press calibrator STBY and disconnect from multimeter.
(8) Connect TI OUTPUT 200 Hz-80 MHz 50 Ω, through 50 Ω feed-through
termination, to multimeter INPUT HI and LO terminals.
(9) Press FREQUENCY, 100, kHz/+dBm, AMPLITUDE, 13.01, and kHz/+dBm
pushbuttons.
(10) Note multimeter reading. If reading does not indicate between the recorded
indication #1 and indication #2 readings, perform b below.
