Total Onboard Memory Used = 1,281,408 bytes
2. An application requires using six waveforms with the following sizes:
480; 260; 960; 492; 516; and 604 samples. The waveforms are
generated by using Arbitrary Sequence mode and Burst trigger mode
to configure 10,000 segments in a sequence list. The following table
shows all the numbers used to determine the total memory stored in the
onboard memory: 135,296 bytes.
