TRIGGER I
35. TRIG MODE-Determines the mode of trigger
operation for A Sweep. I
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.
SINGL SWP: When this pushbutton is pushed, the A
Sweep operates in the single sweep mode.
After a single
sweep
is displayed, further sweeps cannot be presented
until the SINGL SWP button is again pushed. It is useful
when the signal to
be displayed is not repetitive or varies in
amplitude, shape
or time causing an unstable conven-
tional display. It can also
be used to photograph a
nonrepetitive signal.
36. READY
Lamp-Indicates A Sweep is "armed" and,
upon receipt
of an adequate trigger signal, will present a
single-sweep display.
