3457A
4-71, Equipment Required. An AC Signal Source capable of providing sine-wave voltages of 300 mV, 3 V,
and 30 V (+ 0.05%) at a frequency of | KHz is required for the following procedure.
1, Set the HP 3457A to the AC Voltage function (ACV).
2. Connect the AC Signal Source to the HP 3457A front panel HI and LO input terminals. Set the
Signal Source for an output voltage of 30 V at a frequency of 1 KHz.
3. Use the Test Record to record the 300 mV, 3 V and 30 V full-scale readings beginning with the
30 V range.
4. If any of the gain reading
are beyond the limits specifies

1 in Table 4-22 and on the Test Record,
the instrument should be calibrated or repaired. Refer to Section V for calibration procedures.
4-73. Equipment Required. An AC Signal Source capable of providing sine-wave voltages of 300 mV and
3 V (£.2%) at 20 KHz, 300 mV and 3 V (+.1%) at 100 Hz and 300 mV and 3 V (4.3%) at 20 Hz is required
for this test.
|. Connect the AC Signal Source to the HP 3457A front panel HI and LO input terminals. Set the AC
Voltage Standard for an output voltage of 300 mV at a Frequency of 20 KHz.
