For direct connection to instruments such as portable oscilloscopes and graphical multimeters used in labs or the field, the Model 6273 is a fully insulated 50 ohm BNC coaxial cable designed for maximum protection against shock hazards. The assembly uses RG-58C/U cable and has a flexible strain relief molded directly to the cable jacket to restrict bending and prevent impedance changes. The cable is rated at 500 VRMS maximum.
