Product Description
The 3M
™
ScanEM-C 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 ScanEM-
EC Probe detects the electric component of the electromagnetic field and the
ScanEM-HC Probe reacts to the magnetic component. Knowing which is
more prominent is helpful when it comes to engineering a solution.
What is EMC?
Î
If you are new to the world of electromagnetic compliance, please refer to a
brief primer on page 23 of this User’s Guide.
The ScanEM-C Kit offers a universal solution to electromagnetic
compliance problems. By themselves, ScanEM-C Probes are completely
self-contained EM field detectors. When connected to test equipment,
ScanEM-C Probes become broadband amplified near-field probes.
In a stand-alone mode, ScanEM-C Probes indicate the presence and 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, ScanEM-C Probe doesn’t provide absolute levels. It serves only
to single out the areas with relatively high emissions.
As a probe, the ScanEM-C Probe provides both AC and DC outputs.
ScanEM-C Probes serve as: broadband amplified probes for a spectrum
analyzer; as non-contact high-bandwidth voltage (ScanEM-EC Probe) and
current (ScanEM-HC) probes for an oscilloscope; and as broadband field
strength probes for a multimeter and other instruments.
