Verifying AC voltage
Check AC voltage accuracy by applying accurate voltages from the AC voltage calibrator to the
Series 3700A analog backplane connector and verifying that the displayed readings fall within
specified limits.
Do not exceed 300 V
PEAK
between INPUT HI and INPUT LO, or 8 × 10
7
VHz input to prevent
instrument damage.
To verify AC voltage accuracy:
Use shielded low-thermal connections when testing the 100 mV and 1 V ranges to avoid errors
caused by noise or thermal effects. Connect the shield to the output LO terminal of the calibrator.
1. Connect the Series 3700A HI and LO INPUT pins to the DC voltage calibrator as shown in "AC
voltage verification" below.
2. Select the AC volts function.
3. Set the Series 3700A to the 100 mV range. Make sure that relative offset is disabled.
4. Source AC voltages for each of the frequencies and ranges are summarized in the ACV
verification data (on page B-8) table. For each setting, be sure that the reading is within stated
limits.
5. Repeat steps 3 and 4 for each item in the table.
