National Instruments PXIe-4468 - 4. Start the task.; 5. Acquire reading with the DUT.; 6. Measure the frequency using the Extract Single Tone Information VI of the acquired signal around 10 kHz. Compare the measured frequency to the limits in Table 27.; 7. Stop and clear the task. Stop generating a signal with the function generator.

4. Start the task.
5. Acquire reading with the DUT.
6. Measure the frequency using the Extract Single Tone Information VI of
the acquired signal around 10 kHz. Compare the measured frequency
to the limits in Table 27.
7. Stop and clear the task. Stop generating a signal with the function
generator.
Perform Adjustment
AI/AO Gain and Offset Adjustment
Perform an adjustment at least once within the calibration interval.
Adjustment automatically updates the calibration constants, the date, and
the temperature in the DUT EEPROM. If the DUT passes the verification
procedures within the As-Left test limits, an adjustment is not required.
Proceed to the Update the Onboard Calibration Information section.
Note
Initial test connection is same as AI Offset, as shown in Figure 1 or
Figure 2.
