The MK4 EMI compensation system is the latest product in a historically long product range of EMI compensation systems from Integrated Dynamics Engineering. It uses the advantages of former products like MK1 and MK3, forming a hybrid control concept for both AC and DC disturbance. It enables fully host-controlled parametric adjustments, using a standard RS232 ANSI terminal. The hybrid control concept is completely transparent to the user, resulting in an easy-to-control, easy-to-install product with its highest performance in a broadband frequency range, starting at DC (0 Hz) up to several kHz. It offers a reduction of disturbance field amplitudes of typically more than 45dB. Options available from IDE include sensor mounting kits for most SEM and TEM models. Helmholtz cages are custom-built into your room or may be ordered as prefabricated kits.
