A G R E AT E R M E AS U R E O F CO N F I D E N C E essential to use triaxial cables for these measurements. Figure 1 illustrates how these measurements can be made using four triaxial cables. The measurement signal is carried on the center conductor, the inner shield is driven as a guard for the signal, and the outer shield is used for safety to shield the user from high voltages that may be applied to the guard and signal conductors. Two cables are necessary in order to achieve a remote sense, or Kelvin, connection on Need More each device terminal. Remote sense cables allow the instrument to sense the voltage at the device accurately. In this figure, the Measurement device to be characterized has two terminals. CV Measurements' Flexibility? Cabling Requirements Figure 2 illustrates the cabling for C-V Maybe You Need measurements using four coaxial cables. The outer shells are connected together to con- trol the characteristic impedance the signals More
