Product Description
The 3M
™
ScanEM-QC Electromagnetic Near-Field Probes detect the
presence of an electromagnetic field and indicate its relative strength. The
probes are most effective in the near field (close to the radiating object).
The 3M
™
ScanEM-EQC Probe detects the radiated electric component of
the electromagnetic field and the 3M
™
ScanEM-HQC Probe reacts to the
magnetic conductive emission propagated over the cables.
What is EMC
Î
If you are new to the world of electromagnetic compliance, please refer to a
brief primer on page 25 of this User’s Guide.
What about ESD?
Î
For a brief primer on ESD Audit using electromagnetic field tools, please see
page 27 of this User’s Guide.
The ScanEM-QC Kit offers a universal solution to electromagnetic
compliance problems. By themselves, the ScanEM-QC Probes are
completely self-contained EM field detectors. When connected to test
equipment, the ScanEM-QC Probes become broadband amplified near-field
probes.
In stand-alone mode, the ScanEM-QC Probes indicate the presence and
relative strength of an electromagnetic field by two means: audio indication
and an LED level bar. The more LEDs that are on and the higher the
pitch of the sound, the stronger the electromagnetic field is at the point of
measurement. In stand-alone mode, the ScanEM-QC Probe doesn’t provide
absolute levels. It serves only to single out the areas with relatively high
emissions.
