Extremely small probes for direct measurement of high frequency magnetic fields on modules such as IC pins, tiny conductors or around the smallest packaged SMD devices!

Due to the continuous improvement of integrated circuit integration and clock rate, there are a large number of stray magnetic fields and stray currents on the PCB, which are coupled with each other in the form of magnetic fields, resulting in radiation disturbances above GHz. The CISPR22 standard requires the measurement frequency to be 6 GHz. Due to the large number of high-density SMD components mounted on the PCB, only using high-resolution probes can really identify the problem.

A new generation of handheld active miniature magnetic field probe, with frequency coverage from 1MHz to 6GHz, resolution up to 300μm, oscilloscope or spectrum analyzer connected to 50Ω input, used for detailed magnetic field on PCB board layout, components and IC pins Measurement, can selectively measure integrated circuit pins or SMD surface mount devices, use the MFA-R0.2-6 magnetic field probe to diagnose high frequency magnetic field problems up to 6G.

The miniature magnetic field probe has a built-in amplifier and comes standard with a T-type bias device to supply power to the built-in amplifier. The T-type biaser has an impedance of 50Ω and provides stable power supply for the miniature magnetic field probe. Both the miniature magnetic field probe and the bias tee are SMA connectors.

Features:

◆ Two optional: OIMFA-R0.2-6: 100MHz~6GHz

OIMFA-R0.2-75: 1MHz~1GHz

◆ High-resolution magnetic field probe: resolution up to 300μm

◆ Used to measure the smallest package SMD device on the PCB

◆ With the help of the calibration curve, the output voltage of the probe can be converted into the corresponding magnetic field

◆ Accurately measure the high-frequency magnetic field of wiring, components and IC pins on PCB

◆ Lightweight and compact, hand-held operation

◆ Standard: T-bias device and power supply
