EEPROM Update
After completing a verification procedure, complete the following steps:
1.
Open a calibration session for the NI PXIe-4610. The default password is
NI
.
2.
Store the calibration temperature.
a.
Record the ambient temperature.
b.
Call the DAQmx Set Temperature DSA Calibration function to store the calibration
temperature measured in step a.
3.
Store the calibration constants.
a.
Perform steps 1 through 9 of the
Gain and Residual Offset Verification
section to
calculate the
ResidualOffset
of each channel for which you want to update the offset
calibration constant.
b.
Continue with steps 10 through 12 of the
Gain and Residual Offset Verification
section to calculate the
UnadjustedGain
of each channel for which you want to update
the gain calibration constant.
c.
Call the DAQmx Adjust DSA Power Amplifier Calibration function for the
NI PXIe-4610 and configure it as shown in Table 6.
d.
Repeat steps a through c for each channel for which you want to store a calibration
constant.
4.
Close the calibration session.
Accuracy Under Calibration Conditions
The following calibration specifications are valid for the following conditions:
•
Ambient temperature is 23 °C ± 5 °C.
•
PXI Express chassis fan speed is set to HIGH and has clean fan filters.
•
Empty slots have filler panels installed.
Note
The test limits listed in Table 4 and 5 are derived using the values in Table 6
and 7, respectively.
