ScanEM probes
NEAR-FIELD DETECTORS FOR EASY MEASUREMENT OF ELECTROMAGNETIC EMISSIONS
Shorten your development schedule and eliminate the need for product redesign by using proper
EMC tools from the beginning of the project. ScanEM probes are diagnostic instruments for detecting,
locating and measuring electromagnetic emissions. They are professional tools that don’t require
you to be an EMC expert to completely address emission compliance. They can reliably predict
electromagnetic behavior of your products and locate emission sources in a matter of seconds. They
detect the presence of an electromagnetic field and provide audio and visual indication of its relative
strength either working by themselves, or as broadband active probes with any spectrum analyzer,
oscilloscope or multimeter.
• Pinpoint exact sources of EMI
• Detect electric and magnetic fields separately
• Self-contained: palm-sized, no cords, no power supply or amplifier
• Audio output: tone changes indicate field strength
• LED color bar verifies relative field strength
• Squelch feature nullifies ambient to locate problem areas
• Output to spectrum analyzer or oscilloscope if desired
• DC output to multimeter for DC voltage as a function of field strength
• No disturbance of circuit under test - does not touch the circuit
WHY NEAR-FIELD TESTING?
The standard radiated EMC test is done in the far field at 10’-0” (3M) from the product. This shows
if there is a failure, but does not pinpoint the source of the problem. A near-field probe is a close-up
inspection which permits quick product scanning for problem areas.
A day spent at the beginning of a project preventing EMC problems saves days, even weeks, fixing these problems at the end.
