An application requires using five waveforms with the following sizes:
10,000; 1,000,000; 2,000,000; 30,000,000; and 5,000 samples. The
waveforms are generated by using Arbitrary Sequence mode and
Stepped trigger mode to configure 2,000 segments in a sequence list.
The following table shows all the numbers used to determine the total
memory stored in the onboard memory: 66,190,464 bytes.
