Near Field Sniffer Probes AZ530

(Optional)

Near Field Sniffer Probes AZ530 The AZ530

is the ideal toolkit for the investigation of RF

electromagnetic fields. Lt is indispensable of

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 100KHz to over 1000MHz.

The probes-ove magnetic field probe, one

electric field probe, and one high impedance

Probe are all matched to the 50

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 AT6010/AT6011 series

spectrum analyzer.

Signal feed via a 1.5m BNC-cable. When used

in connection with a spectrum analyzer or

measuring receiver, the probes cable used to

locate and qualify EMI sources, as well as

evaluate EMC problems 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 H-Field Near-Field probe

The H-Field probe provides a voltage to the

connected measurement system which is

proportional to

the magnetic radio

frequency (RF) field

strength existing at the

AZ530-M

probe location, With this

probe, circuit therefore sources may be

localized in close proximity of each other. The

H-Field will decrease as the cube of the

distance from the source, A doubling of the

distance will reduce the H-field by a factor of

eight (H=1/d ). where d is the distance.

In the actual use of the H-field sensor one

observes therefore a rapid increase of the

probe's output voltage as the interference

source is approached. While investigating a

circuit board, the sources are immediately

obvious. It is easily noticed which component

(i.e.IC) causes interference and which does not.

in addition. by use of a spectrum analyzer the

maximum amplitude as a function of

frequency is easily identified. Therefore, one

can eliminate early in the development

components which are not suitable for EMC

purposes. The effectiveness of

countermeasures can be judged easily. One can

investigate shields for eaking areas and

cables or wires for conducted interference.

The High-Impedance probe

The high-impedance probe (Hi-Z) permits the

determination

of the radio

frequency

interference (RFI) on

AZ530-H

individual contacts or

printed circuit traces. It is a direct-contact

probe. The probe is of very high impedance

(near the insulation resistance of the printed

circuit material) and is loading the test point

with only 2pF (80

at 1GHz). Thereby one
