Tuning Needles
Tuning needles—which divide a given tuning zone into
thirty “increments”—are used to peak a laser output. As
the top or bottom of a zone is reached, the tuning needles
automatically move to the center of the next zone (see
Figure 8). Zone indicator bars let you know when this
happens (refer to “Zone Indicator Bars” on page 20 for
more information).
