AWG index modes
The arbitrary waveform generator supports single, dual and quad index modes to
help you make the best use of the waveform buffer.
Single mode. The generator outputs the raw
contents of the buffer repeatedly. This mode is
the only one that can generate asymmetrical
waveforms. You can also use this mode for
symmetrical waveforms, but the dual and
quad modes make more efficient use of the
buffer memory.
Dual mode. The generator outputs the
contents of the buffer from beginning to end,
and then does a second pass in the reverse
direction through the buffer. This allows you
to specify only the first half of a waveform
with twofold symmetry, such as a Gaussian
function, and let the generator fill in the other
half.
Quad mode. The generator outputs the
contents of the buffer, then on its second pass
through the buffer outputs the same data in
reverse order. On the third and fourth passes
it does the same but with a negative version
of the data. This allows you to specify only the
first quarter of a waveform with fourfold
symmetry, such as a sine wave, and let the
generator fill in the other three quarters.
