5. 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 5 for the current iteration.
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 5412. This value is the
Measured Positive
Offset Value
.
8. Calculate the error for positive offset using the following formula:
Error Positive Offset
= (
Measured Positive Offset Value
) - (
Ideal Positive Offset Value
)
Compare this error to the
Published Specification
or the
Calibration Test Limit
listed in
Table 5.
9. Call
niFgen_AbortGeneration
(niFgen Abort Generation VI) to abort the waveform
generation using the following parameter:
•
vi
: The session handle returned from
niFgen_init
10. Call
niFgen_SetAttributeViReal64
to set the offset (niFgen property node:
Arbitrary Waveform Output»Arbitrary Waveform Offset
) using the following
parameters:
•
vi
: The session handle returned from
niFgen_init
•
channelName
:
"0"
•
attributeID
:
NIFGEN_ATTR_ARB_OFFSET
•
value
: The
Ideal Negative Offset
value listed in Table 5 for the current iteration.
11. Call
niFgen_InitiateGeneration
(niFgen Initiate Generation VI) to initiate the
waveform generation using the following parameter:
•
vi
: The session handle returned from
niFgen_init
12. Measure the negative DC voltage out of the NI 5412. This value is the
Measured Negative
Offset Value
.
13. Calculate the error for positive offset using the following formula:
Error Negative Offset
= (
Measured Negative Offset Value
) - (
Ideal Negative Offset Value
)
Compare this error to the
Published Specification
or the
Calibration Test Limit
listed in
Table 5.
