3. Call niFgen_SetAttributeViInt32 to set the offset DAC value
(niFgen property node: Calibration»Offset DAC Value) using the
following parameters:
vi: The session handle returned from niFgen_InitExtCal
channelName: "0"
attributeID: NIFGEN_ATTR_OFFSET_DAC_VALUE
value: 32000
4. Repeat steps 5 through 8 for each of the 10 iterations listed in Table 8,
changing the Analog Filter Enable, Pre-Amplifier Attenuation, and
Current Configuration values for each iteration.
5. Call niFgen_SetAttributeViBoolean to set the analog filter state
(niFgen property node: Output Attributes»Analog Filter Enabled)
using the following parameters:
vi: The session handle returned from niFgen_InitExtCal
channelName: "0"
attributeID: NIFGEN_ATTR_ANALOG_FILTER_ENABLED
value: The Analog Filter Enable value for the current iteration
from Table 8.
