44472A Wiring Information
Regardless of the topology (configuration) you are using, always use 50 Ω
shielded coaxial cables to maintain both characteristic impedance and
isolation. Keep cables as short as possible, especially in high frequency
circuits or pulse circuits where a rise/fall time of less than 50 nsec is
critical. Long cables can add considerable delay time which may cause
timing problems. All test equipment (counters, spectrum analyzers,
oscilloscopes, etc.) must be terminated with a 50 Ω impedance to
minimize reflection loss. The rear panel is shown below.
