User-Defined Sequences - Reference
The elements of the Sequence Editor and the dialog boxes that can be opened from
the Sequence Editor are described below:
Sequence Block Display
A new sequence consists of one block that is infinitely repeated (looped). By
default, this block has a length of 512 bits and generates a Pause0 signal (a
continuous stream of zeros). All this is shown on the display.
The vertical waveform at the left-hand side of the block indicates the setting of the
pattern generator's Trigger/Ref Clock Out port. By default, it generates a pulse, a
subrate of the present clock. For information on how to change the trigger behavior,
see “Sequence Trigger at Block Begin” on page 102.
Number of Blocks
In the Blocks field, you can directly specify the number of blocks (up to 120).
