Selecting the Waveform Sequence
This section shows how to select and output an arbitrary waveform without
aborting the current waveform and re-initializing the AFG.
The Waveform
Sequence Registers
The following Waveform Sequence Registers are used to change the output
waveform sequence:
• Traffic Register:
base_addr + 8
16
• Waveform Select Register:
base_addr + A
16
• Sequence Base Register:
base_addr + 20
16
• Status Register:
base_addr + 2
16
The Traffic Register The Traffic Register specifies the source which selects the waveform
sequence.

Sequencer Data Source: The Sequencer data source field specifies the
source which selects addresses in sequence base memory that, in turn, select
the waveform sequences. The available sources are:
0 0 = sequencer data source is Local Bus
0 1 = sequencer data source is Front Panel
1 0 = sequencer data source is Waveform Select Register
The source specified in the Sequence Selection program is the Waveform
Select Register. Note that when the sequencer data source is specified, the
contents of the other register fields must remain unchanged.
