The A100-1 set is used for oscillating analog signals under EFT/ESD/RF interference. The set is particularly suitable for the measurement of analog signals when testing the immunity of electrical or electronical devices (equipment) against high-frequency electromagnetic fields (IEC 61000-4-3 to IEC 61000-4-6). This system is suitable for signal control in an anechoic chamber or EMC-compliant space. The set consists of a sensor which measures an analog signal within the device under test and transforms it into optical signals. The optical signals are transmitted via a fibre optical cable to the optical receiver which then transforms them into electrical signals. Those can be seen with an oscilloscope or can be used for controlling other devices. For signal detecting within the device under test several sensor types AS100, AS110 or AS120 with different measuring ranges are available.

The signal influence of the prescribed modulation models for electromagnetic fields can be easily detected using the A100 set, A200 set and A300 set analog measuring systems. Hard- and software can be EMC-optimized, because disturbed signals can be easily detected.
