*Refer to
Table 17
for details about the correlation between AO Gain, DMM Range, and
Signal Amplitude.
4. Call DAQmx Channel Property Node, and set the AO Idle Output
Behavior property (Analog Output>>General Properties>>Output
Configuration>>Idle Output Behavior) to Zero Volts
5. Call Basic Function Generator Parameters using the parameters
in
Table 22
.
Table 22:
Basic Function Generator Parameters
Parameter Value
Signal Type Sine Wave
Frequency 1000 Hz
Amplitude* Amplitude from
Table 17
Sampling Info>>Sampling Rate 200000 S/s
Sampling Info>>Number of Samples 10000
*Refer to
Table 17
for details about the correlation between AO Gain, DMM Range, and
Signal Amplitude.
6. Write the resulting waveform to AO and start the task.
7. Measure the output voltage with the DMM, and record as V
1kHz
for
future calculations. The first measured amplitude represents
V
1kHz
referenced in
Table 20
. Subsequent test points will be
calculated based on V
1kHz,
as shown in
Table 20
.
8. Stop the task.
9. Compare the result with the limits in
Table 20
.
