Tektronix 314 Manual

d. Set TIME/DIV switch to .2 ms and Sine-Wave Generator
frequency to 1 kHz.
e. Turn 314 LEVEL control through its range and note
that the triggering point on the displayed signal changes.
Note that the triggering occurs on the positive-going slope
of the displayed signal.
f. Set SLOPE switch to — . Note that triggering occurs on
the negative-going slope of the displayed signal. Turn
LEVEL control to either extreme position and note that
the triggering point reaches either a peak or a valley, and
that the sweep is no longer triggered (free runs).
g. Press NORM button in.
h. Turn LEVEL control throughout its range and note that
when the sweep is not triggered, the signal is not displayed.
When the sweep is triggered the LEVEL control sets the
point at which triggering occurs.
Triggering from an External Source
a. Connect the Sine-Wave Generator signal through a tee
connector to CH 1 VERT INPUT connector and to the EXT
TRIG OR HORIZ INPUT connector on the right-side panel.
b. Set EXT ATTEN switch (side panel) to X10 and set
INT button to the out (EXT/LINE) position.
c. Set SLOPE switch to + and LEVEL control to midrange.
d. Press AUTO button in.
e. Set CH 1 VOLTS/DIV switch to .5.
f. Adjust Sine-Wave Generator for a 4 div vertical display
(200 mV, p-p) into EXT TRIG OR HORIZ INPUT connec 
tor.
g. Turn LEVEL control and note that the sweep is triggered
on the positive-going slope.
h. If manual triggering is desired, press NORM button in
and check triggering as in part h.
i. Set SLOPE switch to — and check triggering as in part h.
INTERNAL AND EXTERNAL SWEEP
As with triggering, most applications call for operation using
internal sweep. The internal sweep rate is set by the TIME/
DIV switch, which permits accurate time and frequency
measurements when the TIME/DIV VARIABLE control is
in the calibrated (CAL) position.
External sweep or horizontal deflection for the 314 can be
used for X-Y displays or for mating the oscilloscope to a
