12. 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 4 for the current iteration.
13. 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 8 (positive full-scale handle).
