3. Call
niFgen_SetAttributeViBoolean
to set the analog filter state (NI-FGEN
Analog Filter Enabled property) using the following parameters:
•
vi : The session handle returned from
niFgen_init
• channelName :
"0"
• attributeID :
NIFGEN_ATTR_ANALOG_FILTER_ENABLED
• value :
VI_FALSE
4. Call
niFgen_SetAttributeViReal64
to set the load impedance (NI-FGEN Load
Impedance property) using the following parameters:
•
vi : The session handle returned from
niFgen_init
• channelName :
"0"
• attributeID :
NIFGEN_ATTR_LOAD_IMPEDANCE
• value :
10000000000
5. Call
niFgen_SetAttributeViInt32
to set the analog path (NI-FGEN Analog Path
property) using the following parameters:
•
vi : The session handle returned from
niFgen_init
• channelName :
"0"
• attributeID :
NIFGEN_ATTR_ANALOG_PATH
• value :
NIFGEN_VAL_MAIN_ANALOG_PATH
6. Call
niFgen_SetAttributeViReal64
to set the output impedance (NI-FGEN Output
Impedance property) using the following parameters:
•
vi : The session handle returned from
niFgen_init
• channelName :
"0"
• attributeID :
NIFGEN_ATTR_OUTPUT_IMPEDANCE
• value :
50
7. Call
niFgen_SetAttributeViBoolean
to enable the analog output (NI-FGEN Output
Enabled property) using the following parameters:
•
vi : The session handle returned from
niFgen_init
• channelName :
"0"
• attributeID :
NIFGEN_ATTR_OUTPUT_ENABLED
• value :
VI_TRUE
8. Create an array of waveform samples for the positive full-scale DC waveform. This array
should contain 500 samples with each sample having the value
1.0
(representation:
double).
9. (LabVIEW Only) You must call the Initialize Array function to create the array of samples
for step 8. Wire 1.0 to the
element input and specify a dimension size of 500. Wire the
initialized array output of the Initialize Array function to the Waveform Data Array
input of the niFgen Create Waveform (DBL) VI in step 10.
