Oscilloscopt: Connections to
Curve Tracer
Test leads connecting the curve tracer to the os
cilloscope should be set-up as follows:
CURVE TRACER
OSCILLOSCOPE
V jack ........... Vertical Input
H jack ........... Horizontal Input
G jack ........... Chassis Ground
Once the oscilloscope has been calibrated, the
calibration steps need not be repeated until the
hook-up has been dismantled and made anew, or
the setting of the vertical and horizontal gain con
trols of the oscilloscope have been tampered with.
An occasional recheck of calibration is suggested,
since it is easy and quick to perform.

Plug-in Transistors
The curve tracer contains two identical sockets
into which most small signal transistors or FET's
may be inserted. Either the left or right socket may
be used, but the SOCKET switch must be in the left
position to activate the left socket or in the right
position to activate the right socket. This is very
convenient for selecting matched pairs because the
curve tracer can be instantaneously switched from
one semiconductor to the other. The SOCKET switch
may also be used to start and stop the test of the
semiconductor; merely activate the empty socket to
stop the test. This allows complete removal of test
signals while inserting and removing semiconduc
tors from the socket.
The collector, base and emitter of the transistor
(drain, gate and source of FET) are inserted into the
correspondingly labelled pins of the socket.

For transistors with a grounded case, the fourth
pin can either be inserted into the socket along with
the EMITTER lead or externally jurnpered to either
of the 2 yellow EMITTER jacks.
Non Plug-In Transistors
For power transistors, semiconductors with rigid
leads, semiconductors with special lead configura
tion, or for any other reason that prevents use of
the plug-in sockets, test leads may be connected
from the C-D, B-G and E-S jacks to the elements of
the semiconductor. Two sets of jacks are provided,
one set on the left side and one set on the right side
