Schwarzbeck FMZB 1513 Overview

Active, handheld shielded Loop Antenna with nearly constant antenna factor over the entire frequency range (9 kHz – 30 MHz). The active loop antenna is especially suitable for mobile applications, e.g. with a handheld spectrum analyzer. Combined with a CISPR 16 EMI-receiver a convenient fieldstrength measuring system with low noise and pulse measuring capabilities is composed. The robust, milled aluminum housing comes with two 3/8" large camera threads to accept a handle or to be mounted on a tripod (e.g. AM 9144).

The FMZB 1513 is equipped with 10 NiMH-Mignon cells to keep the weight as low as possible for mobile use. 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. Although it is possible to measure during recharging, we do not recommend to do so because of most NiMH chargers operate in pulsed mode and create unwanted disturbance.

Applications

The Active Loop Antenna FMZB 1513 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 (e.g. 16-1-4), MIL, FCC, EN, ISO, ANSI, ETSI and many other standards.

Noise Floor

Displayed noise level of the FMZB 1513 in reference to field strength, measured with a CISPR 16-1-1 compliant measuring receiver.

The uncorrected voltage display of an EMIreceiver in dBµV must be added with the antenna factor for fic. E -fieldstrength (+20 dB/m) to obtain the field strength-related noise-floor of the system. The figures show the measured noise floor related to field strength for the FMZB 1513 at the FCLE 1535 receiver for different detectors and bandwidths.

Add the desired signal-to-noise-ratio to calculate the sensitivity of the antenna.
