Note
Initial test connection is same as AI Offset, as shown in Figure 1.
Verification Procedure
Complete the following procedure to verify the AI flatness accuracy.
Repeat 2 times, once for each channel.
1. Connect the AI channel under test to the Calibrator as shown in Figure
1.
Repeat 6 times, once for each gain setting.
Repeat 4 times, once for each frequency in
T
6
.
2. Configure the calibrator to generate an output with the frequency
listed in Table 6 and amplitude listed in Table 7.
