4. Call niFgen_SetAttributeViReal64 to set the gain (niFgen

property node: Arbitrary Waveform Output»Arbitrary

Waveform Gain) using the following parameters:

• vi: The session handle returned from

niFgen_init

• channelName: "0"

• attributeID: NIFGEN_ATTR_ARB_GAIN

• value: The Gain value listed in Table 6 for the current iteration

5. Call

niFgen_SetAttributeViInt32 to choose the positive

full-scale DC waveform (niFgen property node: Arbitrary

Waveform Output»Arbitrary Waveform Handle) using

the following parameters:

• vi: The session handle returned from

niFgen_init

• channelName: "0"

• attributeID: NIFGEN_ATTR_ARB_WAVEFORM_HANDLE

• value: The wfmHandle from step 9 of the Verifying the Main

Analog Path Gain section (positive full-scale handle)

6. Call

niFgen_InitiateGeneration (niFgen Initiate Generation VI)

to initiate the waveform generation using the following parameter:

• vi: The session handle returned from

niFgen_init

7. Measure the positive DC voltage out of the NI PXI-5422. Record the

positive DC voltage out measurement in the Measured Positive

Full-Scale Value column of Table 6.

8. Call

niFgen_AbortGeneration (niFgen Abort Generation VI)

to abort the waveform generation using the following parameter:

• vi: The session handle returned from

niFgen_init

9. Call niFgen_SetAttributeViInt32 to choose the negative

full-scale DC waveform (niFgen property node: Arbitrary

Waveform Output»Arbitrary Waveform Handle) using

the following parameters:

• vi: The session handle returned from

niFgen_init

• channelName: "0"

• attributeID: NIFGEN_ATTR_ARB_WAVEFORM_HANDLE

• value: The wfmHandle from step 11 of the Verifying the Main

Analog Path Gain section (negative full-scale handle)

10. Call

niFgen_InitiateGeneration (niFgen Initiate Generation VI)

to initiate the waveform generation using the following parameter:

• vi: The session handle returned from

niFgen_init
