The main advantages of CCP 9225 are:
• Symmetrical coupling, differences between FEXT and NEXT effects are avoided, therefore testing time is reduced to 50%
• Improved reproducability of the coupling capacity by means of reliable conductor alignment
• Integration of spacers into the coupling plate construction
The coupling plate comes with an N-female connector in the center of the base plate. The spacing between coupling plate and ground is 15 mm. In combination with an impedance converter with high impedant input the overall transducer is nearly constant over a wide frequency range. In cases of 50 Ω equipment being directly connected to the capacitive coupling plate, the transmission rises with 20 dB per decade of frequency. The coupling plate CCP 9225 acts as a capacitive voltage divider. In conjunction with the VHIC 9260 impedance converter and a shunt capacitor at its high impedant input the overall transducer can be varied in a wide range.
