Micro probe MFA-K 0.1-30 with Bias-Tee BT 706
Short description
The MFA 02 set includes two high-resolution near-field micro probes used to measure low-frequency magnetic fields up to 1 GHz, e.g. at signal conductors (150 µm), SMD components (0603-0201) or IC pins. Each hand-guided MFA near-field micro probe has an integrated preamplifier.
The amplifier stage (9 V, 100 mA) is powered via the BT 706 bias tee, which has an impedance of 50 Ohm. The near-field micro probes are connected via the BT 706 to a spectrum analyzer or an oscilloscope.
Langer EMV-Technik GmbH includes correction lines in the scope of delivery. With the help of the correction lines the probe’s output voltage is converted into either the respective magnetic field or the current running through the conductor.

MFA-R 0.2-75
Near-Field Micro Probe 1 MHz up to 1 GHz
The MFA-R 0.2-75 near-field micro probe has an extremely small and high resolution probe head. It is suitable for measuring RF magnetic fields up to 1 GHz on components, e.g. close to IC pins, finest conducting paths or smallest SMD components (0603-0201).

MFA-K 0.1-30
Near-Field Micro Probe 1 MHz up to 1 GHz
The MFA-K 0.1-30 near-field micro probe has an extremely small probe head which functions like a coupling clamp. It allows for current measurements at IC pins and the finest conducting paths. The near-field micro probe is shielded from field lines entering the probe head laterally.

BT 706
Bias Tee for Langer probes
The bias tee is used for the power supply of active near-field probes of the Langer EMV-Technik GmbH, e.g. MFA or ICR. The bias tee is inserted into the signal path between the active near-field probe and the spectrum analyzer or oscilloscope and powered by a plug-in power supply.
