Optionally an 18 GHz upgrade package is available
Purpose
The MEDIUM Compact Diagnostic Chamberä (M-CDC™) is developed with the focus on susceptibility testing.
The M-CDC combines conformity with an enhanced frequency range up to 3 GHz .
Consisting of modules, the installed chamber can be dismantled and re-erected elsewhere. Upgrading to a 3 m chamber is also possible.
Immunity
The M-CDC features superior performance for radiated immunity testing. The highest accuracy is achieved according to IEC 1000-4-3 and EN 61000-4-3 in a 1.5 x 1.5 m uniform plane at 3 m test distance.
The M-CDC is compliant with the above standards. In addition, it performs perfectly up to 3 GHz.
Emission
Radiated emission tests for development and quality control at a 3 m distance can be perfectly covered by the M-CDC. With its fully anechoic layout the time-critical height scan of the receive antenna is no longer needed.
Radiated Immunity
The accuracy achieved to IEC 1000-4-3 and EN 61000-4-3 in a 1.5 x 1.5 m at a 3 m test distance complies with these standards.
As required, 75 % of the 16 points are within the 0 ... + 6 dB accuracy range.
