Operating Instructions — Type 114
both the Type 114 and the oscilloscope (see Section 1 for
external trigger characteristics required).
2. Obtain an externally triggered sweep on the oscillo 
scope.
3. Connect a coaxial cable between the TRIGGER OUT 
PUT connector of the Type 114 and the vertical input of the
oscilloscope.
4. Turn the Type 114 PERIOD switch to EXTERNAL TRIG 
GER. Set the WIDTH switch to 100 µ S. Turn the WIDTH
variable control to CAL. Set the oscilloscope VOLTS/CM
switch to 1 volt. Set the TIME/CM switch to .1 mSEC.
5. Set the Type 114 TRIGGER switch to TRAILING EDGE.
A narrow trigger pulse approximately 3 volts in amplitude
should be visible approximately 1 cm from the start of the
oscilloscope trace.
6. Turn the WIDTH — VARIABLE control and note that the
displayed trigger pulse can be delayed from 10 µ sec to more
than 100 µ sec from the start of the trace. By using the 5
basic ranges of the WIDTH switch and by turning the as 
sociated VARIABLE control, it is possible to delay the trigger
pulse over a range from approximately 150 nanoseconds to
10 milliseconds.
Switching the Power Transformer Primary Con 
nections
A switch on the rear of the Type 114 chassis permits
switching the power transformer connections for operation on
either 94.5-137.5 (115 V ac nominal) or 189-275 volts ac (230
V ac nominal). Be sure the correct fuse is installed.
