to the SYNC clock output. The trigger must be a minimum of two SYNC
clock cycles long. The trigger timing is specified relative to the rising edge
of the SYNC clock. The analog output from the AWGs is then produced a
fixed number of sample clock cycles (plus a small fixed propagation delay)
after the first rising edge of the SYNC clock after the trigger goes active.
Since the analog output is retimed by the sample clock, the reference for
jitter measurements is the sample clock, as shown in
