Key Specifications of Teseq CDN 3425 Capacitive Coupling Clamp

• Mainly used to couple burst/EFT pulses to data lines. It can also be used for mains lines where no CDN is available, such as high - current lines greater than 200 A.

• Designed for conducted immunity testing per EN 61000-4-6 and other EMC standards.

• Injects RF disturbance signals onto cables (e.g., power lines, data lines) without galvanic contact.

Frequency Range:150 kHz to 230 MHz (covers typical immunity test requirements).

Coupling Capacitance:Capacitive coupling via clamp design: 100 pF to 200 pF (depending on cable geometry and setup).

Impedance:150 Ω nominal impedance (matches standard test setups for RF immunity).

Maximum Test Voltage/Current:Up to 200 V RMS (dependent on test setup and safety guidelines).

Current handling compatible with typical EMC test levels.

Mechanical Design:Adjustable clamp for cables up to 30 mm diameter.

Robust construction with shielded housing for minimal external interference.

Connectors:Input: BNC or N-type (RF input from amplifier).

                  Output: Direct coupling to the cable under test.

Compatibility:Works with RF amplifiers and test systems (e.g., Teseq NSG 3000 series, or equivalent).

                        Used in automotive, industrial, and consumer electronics EMC testing.

Standards Compliance:Meets EN 61000-4-6, IEC 61000-4-6, and CISPR specifications for conducted immunity.

Typical Applications of Teseq CDN 3425 Capacitive Coupling Clamp

• Immunity testing for electrical/electronic devices against RF conducted disturbances.

• Pre-compliance and full-compliance EMC testing in labs or production environments.

• Automotive component testing (e.g., ISO 11452-4).

Accessories of Teseq CDN 3425 Capacitive Coupling Clamp

• Optional INA 3425 calibration kit as specified in IEC 61000 - 4 - 4 Ed 3.0 (2012).

• Optional INA 3825 safety cover with interlock function, which can be connected to NSG 3000 series generators.

Technical Characteristics of Teseq CDN 3425 Capacitive Coupling Clamp

• Coupling Capacitance: The coupling capacitance between the clamp and the cable placed in it depends on the cable characteristics.

• Operating Environment: Preferably operated in a screened room to protect the environment. The distances to the EUT (Equipment Under Test) and peripherals should be as specified in the standard. It requires good and large - area contact with the earth plane. Tests on uninsulated cables are not allowed.

• Connection: Connect the provided HV pulse cable to the pulse output of the EFT/Burst generator. If the INA 3825 accessory is used, connect the interlock cable to the interlock input of the generator and use the INA 3825 to cover the CDN 3425 to activate the interlock switch (rear side - middle).
