NI 5122/5124/5142 Calibration Procedure
Vertical Offset and Vertical Gain Accuracy
Table 3 contains the input parameters for verifying both vertical offset accuracy and vertical
gain accuracy of the digitizer.
To verify vertical offset accuracy, complete the procedures described in the
section for each of the 39 iterations in Table 3 for channel 0, then repeat the procedures
for channel 1. The
Calibration Test Limits
and
Published Specifications
for vertical offset
accuracy are shown in Table 4 (NI 5122), Table 5 (NI 5124), and Table 6 (NI 5142).
To verify vertical gain accuracy, complete the procedures described in the
section for each of the 39 iterations in Table 3 for channel 0, then repeat the procedures
for channel 1. The
Calibration Test Limits
and
Published Specifications
for vertical gain
accuracy are shown in Table 7 (NI 5122/5142) and Table 8 (NI 5124).
