While shielded cables are beneficial for DC power supplies by providing noise shielding, their inherent capacitance creates problems for high-frequency applications such as high voltage amplifiers. This cable capacitance causes current to flow, which results in power loss and heat generation. Furthermore, it can introduce a phase shift and reduce the amplifier's upper frequency bandwidth. To avoid these adverse effects, unshielded cables are used for the output of our high voltage amplifiers to ensure optimal performance.
