CDG 7000-75-10 Magnetic & Conducted Immunity, 10 kHz – 250MHz

CDG 7000-75-10 Magnetic & Conducted Immunity, 10 kHz – 250MHz

The CDG 7000 is a new test generator for all standards on immunity to conducted disturbances induced by high-frequency fields – including BCI tests (ISO 11452-4). One of the very few combined IEC 61000-4-6 test systems that contain the RF signal generator, an RF power amplifier, a 3-channel RF voltmeter, and a directional coupler at a very affordable price. IEC 60601-1-2 calling out IEC 61000-4-39 magnetic immunity for close proximity testing requirements can also now be met with the 10 kHz unit.

Description

IEC 60601-1-2 ED. 4.1 / IEC 61000-4-39

New requirement, immunity to proximity magnetic fields based on IEC 61000-4-39

  • IEC / EN 61000-4-6
  • IEC 61326-3-2
  • NAMUR
  • MIL-STD-461 / DO-160
  • IEC 60601-1-2 Ed.4.1 to IEC 61000-4-39 (Close Proximity Magnetic immunity) see below
  • Please check out CDG 7000 page for the general specification of the generator

 

The IEC 60601-1-2 standard is the international standard for testing medical equipment to EMC. The latest update adds a new test as more transmitter products are present in homes, offices (locations where medical equipment may be used), and hospitals. Three frequencies that are in use are: 30 kHz, 134.2 kHz, and 13.56 MHz. The standard IEC 61000-4-39 for testing fields in close proximity is referenced for this testing. With our IEC 60601-1-2 setup these test fields can be produced.

CDG 7000-75-10 - Magnetic and Conducted Immunity, Induced HF, 9 kHz - 250 MHz requirements

The magnetic loops are specified in IEC 61000-4-39 and are readily available. However, producing a field through the loops might not be straightforward. The loop impedance changes over its frequency range and the amplifier being used will not match this impedance. The result would be a much higher power requirement. In this case, we are not covering a frequency range but individual frequency points. This allows a matching network to be created to match the loop to the amplifier’s impedance.
