Comments • SCPI commands are included in this program to load segment and
sequence memory, and initialize the AFG. This program executes as
intended when the SCPI commands are executed prior to writing to
the registers.
• The sequence in which the Waveform Selection Registers are written
to and the register contents are summarized below.
The Traffic Register selects the source which specifies addresses in
sequence base memory that, in turn, select the waveform sequences.
The Waveform Select Register (selected by the Traffic Register)
contains the waveform index which is the location in sequence base
memory where the base address of the sequence in sequence memory
is located.
