FMZB 1512 - Active Handheld Receive Loop Antenna


  • Schwarzbeck FMZB1512

The FMZB 1512 is an active, shielded handheld loop antenna with nearly con- stant antenna factor over the entire frequency range. It can be used for testing according to CISPR, MIL, FCC, EN, ISO, ANSI, ETSI and many other standards.

It can be used for the frequency selective measurement of magnetic fields (or fictive electric field) in the frequency range from 9 kHz to 30 MHz.

The active loop antenna is especially suitable for mobile applications, for instance if used with a handheld spectrum analyzer. Combined with a CISPR 16 EMI-receiver the FMZB 1512 makes a convenient field strength measuring system with low noise and pulse measuring capabilities.
