12. Stop the task using the following function.
13. Clear the task using the following function.
14. Repeat steps 3 through 13 for all remaining gain values used in step 6.
Also modify the device output amplitude used in step 3. For all values,
refer to Table 5.
15. Repeat steps 1 through 14 for analog output channel 1 of the device.
Replace
ao0 with ao1 in the function call parameters

Verifying Timebase Frequency Accuracy
This section describes the verification process for the timebase frequency
accuracy on all the NI 446X devices. All analog inputs use a single circuit
on each device. The NI 4461 analog output channels also use the same
timebase frequency circuit. Therefore, you need to verify only the analog
input frequency accuracy on a single channel to verify this circuit accuracy.
Complete the following steps to verify the timebase:
1. Connect the function generator to the analog input channel 0 of the
device.
2. Output a sine wave using the function generator. The sine wave should
have an amplitude of 9 V
p-p
with no DC offset and a frequency of
10,000.00 Hz.
