TRIGGER
(BOTH A AND B IF APPLICABLE)
Refer to Figure 4 for location of items 27 through 35.
@TRIG MODE Switches- Three push button switches
determine
the mode of trigger operation for the A
Sweep.
AUTO-Sweep is initiated by the applied trigger
signal.
In the absence of an adequate trigger signal,
or if the trigger repetition rate is less than about
20 hertz, the sweep free runs and provides a bright
reference trace.
NORM-Sweep is initiated by the applied trigger
signal.
In the absence of an adequate trigger signal,
there is no trace. When the trigger rate is too low
for AUTO, use NORM.
SINGLE SWP-When this push button is pressed,
the A Sweep operates in the single-sweep mode.
After a single sweep is displayed, further sweeps
cannot be presented until the SINGL SWP push
bu'tton
is again pressed. SINGL SWP is useful in
displaying and photographing either nonrepetitive
signals or signals that cause unstable conventional
displays (e.g., signals
that vary in amplitude, shape,
or time).
