OPERATING CONSIDERATIONS
This section contains basic operating information
and techniques that should be considered before
attempting to make any measurements with the
instrument .
Grounding
The most reliable signal measurements are made
when the oscilloscope and the unit under test are
connected by a common reference (ground lead)
in addition to the signal lead or probe. The probe ' s
ground lead provides the best grounding method
for signal interconnection and ensures the maxi-
mum amount of signal-lead shielding in the probe
cable.
Signal Connections
Probes
Generally, the accessory probes supplied with the
instrument provide the most convenient means of
connecting a signal to the vertical inputs of the in-
strument. The probe and probe lead are shielded
to prevent pickup of electromagnetic interference .
Both the probe itself and the probe accessories
should be handled carefully at all times to prevent
damage. Striking a hard surface or dropping the
probe body can cause damage to both the probe
body and the probe tip . Use care to prevent the
cable from being crushed or kinked, and do not
place excessive strain on the cable by pulling it .
Coaxial Cables
Cables used to connect signals to the vertical input
may have considerable effect on the accuracy of a
displayed waveform . To maintain the original fre-
quency characteristics of an applied signal , only
high-quality , low-loss coaxial cables should be
used. Coaxial cables should be terminated at both
ends in their characteristic impedance to prevent
signal reflections within the cable.
