EMV Near-Field Probe Set up to 1GHz
The HZ530 Probe Set consists of three active broadband probes for EMI diagnosis. The probes are designed for connection to a HAMEG spectrum analyzer with input impedance of 50 Ω. The probes can be powered by the spectrum analyzer or batteries. The slim format ensures easy access to the test object even in cramped test environments.
The H-field probe provides a signal that is proportional to the magnetic field strength to the spectrum analyzer. This makes it possible to localize sources of interference with relatively high precision.
The high-impedance probe can be used to determine interference levels on contacts, lines and printed circuit boards.
The E-field probe is the most sensitive of the three probes. It can be used to assess the total effect of shielding and filtering in a tested unit.

| | | HZ540/HZ550
EMV Near-Field Probe Set up to 3GHz
The HZ540/550 are the ideal toolkits for the investigation of RF electromagnetic fields. They are indispensable for EMI pre-compliance testing during product development, prior to third party testing. The sets include 3 or 5 hand-held probes with built-in preamplifier covering the frequency range from <1 MHz to approx. 3000 MHz.
The probes of the basic set HZ540 include one magnetic field probe, one electric field probe, and a high impedance probe. In addition to the HZ550 features an optional μmagnetic field probe and an antenna. All probe outputs are matched to the 50 Ω inputs of spectrum analyzers or RFreceivers.
