Active, shielded Loop Antenna with nearly constant antenna factor over the entire frequency range (9 kHz - 30 MHz), battery-driven to minimize disturbance influence from the power line.

Applications:

The Active Loop Antenna FMZB 1519 C can be used for the frequency selective measurement of magnetic fields (of fictious electric field) in the longwave, midwave, and shortwave frequency ranges. It can be used for testing according

to CISPR, MIL, FCC, EN, ISO, ANSI, ETSI, and many other standards. Combined with a CISPR 16 EMI receiver a convenient fieldstrength measuring system with low noise and pulse measuring capabilities is composed. The FMZB 1519 C can also be used with a spectrum analyzer. The shielded aluminum housing is equipped with rubber feet for desktop operation or can be mounted to a tripod using the female camera threads (1/4” and 3/8") at the bottom.

The FMZB 1519 C is equipped with 10 NiMH-Mignon cells. The battery voltage is indicated with a green LED for normal operation, with both red and green for reserve and with red only for urgent recharge requirement. It is not possible to measure during recharging.

A full battery charging period using the recommended charger takes around 5 hours. The PWR-switch must be set to OFF during the recharging period, otherwise, no charging takes place! The charging connector is disabled while the PWR switch is set to ON (normal measuring operation), this avoids disturbances generated by the charger having an unwanted influence on the measurement.
