PCD 121 - Coupling Network for Symetrical Data And Control lines
The Haefely PCD 121 is used for coupling of 1,2/50us – 8/20us combination wave impulses up to 6.6kV peak onto unshielded symmetrical data and signal lines according IEC/EN standards. Up to 2 pairs / 4 wires can be tested simultaneously
To obtain maximum flexibility, only coupling elements are included in the PCD 121. Decoupling circuits, which depend on the EUT to be tested, can be placed separately in the test setup.
Manual coupling path switching for common mode (longitudinal, line to earth) as well as differential mode (transversal, line to line) testing. Default coupling elements are gas arrestors and breakdown avalanche diodes.
The coupling elements can be selected easily. The direct coupling output allows the customer to use their own coupling elements.
Key Features
- Combination wave 1,2/50us – 8/20us impulse
- Serial resistors included
- Up to 2 pairs / 4 wires can be tested
- Signal Bandwidth up to >10MHz
- Low capacitive load on the EUT lines
- Manual coupling path selection
- All the sockets use safety banana plugs to ensure maximum safety to the user - The selected coupling path can be seen at a glimpse
- Careful component selection ensures that the PCD 121 will continue to operate under the most strenuous testing regimen
