From MegaPhase RF/Microwave Cables
In most precision test applications-whether in the lab, on the production floor or in the field-cables are constantly moved with repetitive flexures. In all of these applications it is absolutely necessary to have reliable test and measurement components that provided precise electrical stability measurement after measurement. Traditional flexible coaxial cables use braid/foil outer conductors and repetitive flexure causes the braid and foil strands to deform, thereby changing the impedance and compromising the phase and amplitude stability of the cable. Products & Services
Serial cables are used for the serial transmission of data. They support communication standards such as RS232, RS422, and RS485, as well as Fibre Channel, IEEE 1394 or FireWire® (Apple Computer, Inc.), and universal serial bus (USB).
