NI 5114 Calibration Procedure
4.
End the session using the niScope Close VI.
Verification
Note
After the 15-minute warm-up time, always self-calibrate the NI 5114 before
beginning a verification procedure.
This section describes the program you must write to verify either the calibration test limits or
the published specifications for the NI 5114.
Note
If any of these tests fail after you perform an external adjustment, make sure
that you have met the requirements listed in the
and
sections before you return the device to National Instruments for repair.
Vertical Offset and Vertical Gain Accuracy
Table 4 contains the input parameters for verifying both vertical offset accuracy and vertical gain
accuracy of the NI 5114.
To verify vertical offset accuracy, complete the procedures described in the
section for each of the 20 iterations listed in Table 4 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 5.
To verify vertical gain accuracy, complete the procedures described in the
section for each of the 20 iterations listed in Table 7 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 6.
