The most important
advantages, as compared to
GHz-TEM Cells, are the fact that
the personnel can walk into this
chamber therefore simplifying
DUT setup as well as the
possibility of taking larger
test specimen into the chamber.
The UCC can be used for
pre-compliance radiated emission
measurements and immunity tests
according to standard IEC
61000-4-3. In addition, it is
very well suited for pre-compliance
measurements of automotive components
according to DIN/ISO 11452-2 and EN 55025 (CISPR
25).
If required, the UCC can also be used as
a normal shielded room for conducted
emission testing. Because of its small
dimensions, the chamber can be placed in
normal laboratories or offices.
Compact
Hybrid Chambers (CHC)
The CHC presents chambers
optimal solutions for
immunity tests according to
standard EN/IEC 61000-4-3 at
a measuring distance of 3.0m
and offers excellent
characteristics for
pre-acceptance emission
measurements. Ferrite and
hybrid absorbers allow
measurements in the
frequency range from 30MHz
to at least 18GHz.
Chambers can be delivered in
semi-anechoic version (with ground plane) or
as a fully anechoic chamber (floor absorbers
on the whole floor surface). An
automotive testing version is available
suitable for radiation testing of automotive
components according to standard DIN/ISO
11452-2 and EN 55025 (CISPR 25).
CPC
Chambers
The CPC is an anechoic
Chamber for emission
measurements according to EN
55022B and immunity tests
according to EN/IEC
61000-4-3. Frankonia has
succeeded in developing an
inexpensive chamber, which
fulfils the NSA performance
of ±4dB from 30MHz to 1GHz
in a cylinder of 2m
diameter, and 2m height.
This has been achieved using
pyramid absorbers and by the
additional use of specially
developed absorbers. The
chamber thus absolutely
conforms to both emission
measurements and immunity
testing.
Large
anechoic chambers
Anechoic chambers suitable
for 10.0m and beyond
measuring distance are
available as customised
facilities. Planning an
anechoic chamber can be done
in conjunction with
architects and engineers in
order to ensure an optimum
facility. A range of
features are offered
turntables and rolling test
stands or driving pits for
sliding gates. Interfaces to
emergency control and alarm
systems, for example fire
alarm and fire extinguishing
systems, can be taken into
consideration.
