Active, shielded Loop Antenna with nearly constant antenna factor over the entire frequency range (8 kHz – 30 MHz), battery driven to minimize disturbance influence from power line. An overload indicator is activated if an incoming signal approaches or exceeds the 1 dB compression level.
Combined with a CISPR 16 EMI-receiver a convenient field strength measuring system with low noise and pulse measuring capabilities is composed. The robust, milled aluminum housing comes with camera threads to accept a handle or to be mounted on a tripod (e.g. AM 9144). The FMZB 1519 C is equipped with 10 NiMH-Mignon cells.
The Active Loop Antenna FMZB 1519 C can be used for the frequency selective measure-ment of magnetic fields (of fictious electric field) in the longwave, midwave and shortwave frequency ranges. It can be used for testing according to CISPR (e.g. 16-1-4), MIL, FCC, EN, ISO, ANSI, ETSI and many other standards.
