- Commodity name: CA EFT kit Load Resistor Assembly for Electrical Fast Transient Pulse Group Calibration
- Commodity ID: 1064481961155383296
- 品牌11: EMTEST
- 行业: 民用
- 描述: The CA EFT kit contains the required load resistors and a set of adapters to connect the coaxial matching resistors to the output ports of the test device.
- 品牌: EM TEST
The pulse waveforms generated by an electrical fast transient/pulse group generator designed according to IEC 61000-4-4 need to be verified at 50 ohm and 1000 ohm loads at the 50 ohm coaxial high voltage output; and also at 50 ohm loads at the output of the test device connected by the coupling network during power line testing.

The CA EFT kit includes the required load resistors and a set of adapters to connect the coaxial matching resistors to the output ports of the test device.
