HOLDOFF:
Rotation adjusts holdoff time (trigger inhibit period
beyond sweep duration). When control is rotated
fully counterclockwise, the holdoff period is
MIN-
inum (normal). The holdoff period increases pro-
gressively with clockwise rotation.
TRIGger LEVEL:
Trigger level adjustment; determines the point on
the triggering waveform where the sweep is trig-
gered. Rotation in the (–) direction (counterclock-
wise) selects more negative triggering point;
rotation in the (+) direction (clockwise) selects
more positive triggering point.
