The HZ530 is the ideal toolkit for the investigation of RF electroma-
gnetic fields. It is indispensable for EMI pre-compliance testing
during product development, prior to third party testing. The set
includes 3 hand-held probes with a built-in pre-amplifier covering
the frequency range from 100 kHz to over 1000 MHz.
The probes - one magnetic field probe, one electric field probe,
and one high impedance probe - are all matched to the 50 Ω inputs
of spectrum analyzers or RF-receivers. The power can be supplied
either from batteries, Ni-Cads or through a power cord directly
connected to an HM5010/11 series spectrum analyzer.
Signal feed is via a 1.5m BNC-cable. When used in conjuction with
a spectrum analyzer or a measuring receiver, the probes can be
used to locate and qualify EMI sources, as well as evaluate EMC
prob lems at the breadboard and prototype level. They enable the
user to evaluate radiated fields and perform shield effectiveness
comparisons. Mechanical screening performance and immunity
tests on cables and components are easily performed.
The magnetic probe incorporates a high degree of rejection of both
stray and direct electric fields, and provides far greater repeatability
than with conventional field probes. Meas urements can be made
on the very near field area that is close to compo nents or radiation
sources. It is especially suited to locate emission "hot spots" on
PCBs and cables.
The electric field (mono-pole) probe has the highest sensitivity of
all three probes. It can be used to check screening and perform
pre-compliance testing on a com par ative basis.
The high impedance probe is used to measure directly on the
com ponents under test or at the conductive trace of a PC board.
It has an input capacitance of only 2pF and supplies virtually no
electrical charge to the device under test.
