Lower Display mV Source Tests
1. Press M on the UUT until SOURCE appears on the lower display; then press V
until mV appears on the lower display.
2. Set the HP 3458A to measure dc voltage in the 200 mV range.
3. Connect the UUT to the HP 3458A as shown in Figure 7.
4. Use the arrow keys on the UUT to set the UUT output to the current values in Table
15 and verify that the HP 3458A readings are within the limits shown.
5. Press Mon the UUT to disable the sourcing function.
Table 15. Lower Display mV Source Readings
UUT Outputs HP 3458A Readings
0.00 mV -0.020 mV to +0.020 mV
50.00 mV 49.970 mV to 50.030 mV
100.00 mV 99.960 mV to 100.040 mV
Lower Display Voltage Source Tests
1. Press M on the UUT until SOURCE appears on the lower display; then press V
until V appears on the lower display.
2. Set the HP 3458A to measure dc voltage in the 20 V range.
3. Connect the UUT to the HP 3458A as shown in Figure 7.
4. Use the arrow keys on the UUT to set the UUT outputs to the currents in Table 16
and verify that the HP 3458A readings are within the limits shown. A lower voltage
range on the HP 3458A may be used to verify the 0 V range.
