Some guidelines for user input cabling are:

∙For best high-frequency performance, user cabling should have at least two braided shields or one braid and a foil wrap.

∙Always use shielded coaxial cables with the characteristic impedance of the multiplexer used (50Ω or 75Ω). Keep cables as short as possible, especially in high-frequency circuits or pulse circuits where a rise/fall time of <50 nsec is critical.

∙Long cables can add delay time which can cause timing problems. All test equipment, such as counters, spectrum analyzers, and oscilloscopes, must be terminated in the characteristic impedance to minimize reflection loss.

∙To maintain low dc offset voltages, cables should have copper center conductors, not copper-clad steel. RG-233/U cable is recommended. Table 2-1 lists Hewlett-Packard BNCcables which meet these guidelines.
