Introduction：
FMZB 1512 is a Schwarzbeck active shielded handheld loop antenna, the antenna's active design allows it to be built-in a preamplifier, we also designed a switch to control the amount of gain, there are a total of 12 antenna gain can be selected for the full 30MHz band range, of course, the change in gain also leads to changes in the antenna coefficients, please select the appropriate antenna gain to start testing according to the test requirements. Please choose the appropriate antenna gain to start the test according to the test requirements.
12 built-in gain and antenna coefficients available for customer selection

This antenna has an almost constant antenna coefficient over the entire frequency range and can be used for frequency selective measurements of magnetic fields (or simulated electric fields) in the frequency range from 9kHz to 30MHz, in compliance with tests according to CISPR, MIL, FCC, EN, ISO, ANSI, ETSI and many other standards.

- If you need a ring antenna with a diameter of 60cm, you can purchase it:FMZB 1519-60 D
Applications:
The FMZB1512 active loop antenna is particularly suitable for mobile applications, e.g. if used with a hand-held spectrum analyzer, in combination with a CISPR 16 EMI receiver, it can form a convenient magnetic field strength measurement system with low noise and impulse measurement capabilities.
Magnetic and electric field conversion equations:
This antenna requires the use of the following formulas to calculate the generated magnetic and electric fields, contact us for more information on how to use them.
- F [dBµV/m]=G [dBµA/m]+51.5 dB
- E [V/m] = H [A/m] x 377Ω
- F: electric field strength level
- G: Magnetic field strength level
- Z = 120 πΩ = 377 Ω
