Schwarzbeck Mess-Elektronik - CMAD 1614, 10 - 1000 MHz, Common Mode Absorption Device
- Common-Mode Absorbing Clamp
- (10) 30 - 200 (1000)MHz
- Suppress unwanted common mode currents
- Cable bundles maximum diameter of 26 mm
- acc. CISPR 16-1-4
The CMAD 1614 - Common Mode Absorption Device consists of many precision-cut ferrite half-toroids, which are embedded in a grey plastic housing. The unique floating toroid bearing ensures a perfect fit of the ferrite surfaces. Two quick-locks at the long side allow opening and closing of the clamp within seconds. Cable bundles or coaxial cables with a maximum diameter of 26 mm are accepted by the clamp without disassembling connectors or interrupting any circuitry. The combination of short length and large cable hole diameter offers a broad variety of applications for the CMAD 1614. Each common-mode absorption device comes with an individually measured calibration certificate.
The CMAD 1614 can be used for both, coaxial cables and unshielded cable bundles, in order to suppress unwanted common mode currents (also called braid currents). Since these unwanted common mode currents are very often a reason for poor repeatability of measurements, the new CISPR 16-1-4 standard recommends the use of absorbing clamps.

Application
The CMAD 1614 can be used for both, coaxial cables and unshielded cable bundles, in order to suppress unwanted common mode currents (also called braid currents). Since these unwanted common mode currents are very often a reason for poor repeatability of measurements, the new CISPR 16-1-4 standard recommends the use of absorbing clamps.
Calibration
The CMAD 1614 can be calibrated with the optionally available "CAL CMAD 1614" calibration adapter as described in CISPR 16-1-4. The procedure is described in detail in the datasheet of the calibration adapter.

- (50) 75 - 1500 MHz
- 1 kW (w/ 7-16 High power 5.4 kW)
- Type N (female) or 7-16 DIN (f)
The optoCAN-FD system can be used for the bidirectional optical transmission of CAN-signals with transmission rates of up to 10 Mbit/s. It consists of two identical battery supplied transceivers connected to each other with an optical fiber. With the optical transmission and the shielded case, the system is well equipped for EMI and EME tests.
