Acquisition parameters may be set from either the tool bar or the
pull-down menus. The parameters are shown in Table 3.
Once the acquisition parameters are set, click the Run button
(red triangle) in the upper left to begin acquisition. At this point
the analyzer will begin capturing data and after the initial 64K
samples are acquired, sampling will continue until either the
trigger pattern is recognized or the stop button (black square) is
pressed (see Figure 2).
During this period, the status window displays PRE for the
pre-trigger state (although you may not see it if the trigger
pattern is matched quickly).
