100 Series EMC Probes

The 100 series EMC probes are designed for identifying and fixing EMC problems. The 100A, 100B, and 100C are loop probes, and are sensitive to magnetic fields. The 100D is a stub probe, and is sensitive to electric fields.

Features

• An integrated electrostatic shield in the loop probes eliminates common-mode pickup.
• Multiple loop sizes offer optimum sensitivity and spatial resolution at different frequencies.
• Probe dimensions optimized for access to tight spaces.
• Calibrated sensitivity up to 3 GHz, depending on model. Usable to beyond 6 GHz.
• Can be driven by a signal source to generate fields for electromagnetic susceptibility testing.

Applications

• Finding sources of EMC emissions problems.
• Injecting fields into circuits to identify those which are EMC-susceptible.
• Noninvasive probing of RF circuits. The probes can be used to measure the signals present on an
operational PC board.
