EM Test ACC Capacitive Coupling Clamp for ISO 7637 Automotive Testing
The EM Test capacitive coupling clamp ACC is used to couple fast transient pulses to I/O lines as required in different national and international standards and car manufacturer specifications for automotive testing.
The effective coupling capacitance depends on the diameter and the material of the used cables. A typical value will be around 100 pF.
- Strictly acc. to ISO 7637 and many car manufacturer specifications
- Precise construction with highest quality surfaces
- Accept cables up to 40 mm diameter
- Characteristic impedance 50 Ohm
The coupling on signal lines can usually not be effected capacitively without interfering with the signal flow. It is often impossible to contact the required circuit (direct), e.g. coaxial or shielded cables. In this case the coupling is realized with the capacitive coupling clamp. The interference simulator can be connected via a coaxial cable on both sides of the ACC coupling clamp.
