The PCD 150 is used for surge coupling onto unshielded data- and signal lines according to IEC/EN standards. Damped oscillatory waves with both 100kHz and 1MHz up to 3.3kV peak as well as ring wave 100kHz with Z=200 Ohm up to 4.4kV peak can be coupled.

Coupling and decoupling elements are included in one box because of the sensitive impulse shape. Manual coupling path switching for differential mode (transverse mode, line to line) and for common mode (longitudinal, line to earth) testing.

Default coupling and protection elements are breakdown avalanche diodes. Therefore the capacitive load to the EUT lines is low.
