the probe attenuation factor (when Tektronix coded
probes are used).
Coaxial Cables
Cables used to connect signals to the input connectors
may have considerable effect on the accuracy of a
displayed waveform. To maintain the original frequency
characteristics of an applied signal, only high-quality, low-
loss coaxial cables should be used. Coaxial cables must
be terminated at both ends in their characteristic
impedance to prevent signal reflections within the cable.
Use suitable impedance-matching devices.

EXTERNAL TRIGGERING
The A and the B trigger signals are independently
obtainable from a variety of sources. When viewing signals
that require a trigger source different than one of the
displayed signais, a free vertical input channel may be
used to input the trigger signal, The CH 1 and CH 2 verti-
cal input channels may be used to condition a wide range
of signais to produce triggers over the full vertical
deflection range from millivolts to hundreds of volts in
amplitude. The CH 3 and CH 4 vertical input channels
have a choice of two attenuation factors (either divided by
1 or by 5 without the use of external attenuation) and are
especially usefui for triggering on and viewing digital signal
levels.
