A network simulation has the task of supplying the test object (the source of interference) with the operating current, forwarding the interference voltage present at its terminals to the radio interference measuring receiver and loading the radio frequency emitted by the test object with a standardized impedance.
The NSLK 8126 is equipped with a 250 μH pre-choke as well as a 50 μH main choke connected in series for each path. The pre-choke ensures excellent decoupling from the feed network, even at 9 kHz.
