MFA-K 0.1-12 Near Field Probe Langer EMV 100MHz-6GHz

Introduction：

The MFA-K 0.1-12 is a handheld, high-resolution active near-field microprobe from Langer EMV, Germany, which requires a BT 706 T-bias for operation. It can be used to measure magnetic fields up to 6 GHz, especially at signal conductors (150 µ m) or IC pins. In principle, it has the same construction as the MFA-K 0.1-30 and differs only in its frequency response.

Due to the special probe design, magnetic fields impinging laterally on the probe, e.g. from neighboring conductors, are not detected. The direction of the coil is marked on the probe with a black dot.

The amplifier is integrated into the top of the probe. The amplifier (9 V, 100 mA) is powered through a T-bias with an impedance of 50 Ω. The near-field microprobe is connected to a spectrum analyzer or oscilloscope with a 50 Ω input through a BT 706 bias T-connector.

With the help of the correction graph below, you can convert the output voltage of the probe's RF interface into the corresponding magnetic field or current flowing through the conductor.

This near-field microprobe is small and easy to use. It has a current attenuation sheath and is electrically shielded.
