to determine the products inability to function when being exposed to an interfering signal. This interfering signal may be in the form of a carrier wave, modulated signal, spike voltage, or transient event. We can generate Radiated Susceptibility fields across the frequency range of 10 KHz to 40 GHz. We have large anechoic test chambers with high current DC and AC sources available. They are built with echo suppression features and radiation absorbent material to minimize reflection of RF waves... (read more)
