Determining the shielding effciency of housings
What counts from an EMC point of view when choosing or making the "right
packaging" is primarily the level of shielding. In normal cases, the entire frequency
range between 25 and 1000 MHz has to be included in planning. The RSQ-3200
turns this into child`s play. To begin with, the radiation source including the antenna
is inserted in the housing that needs to be tested. As far as small housing are
concerned, an isulated wire acts as the antenna. The frequency range that is
radiated in the housing is recorded initially with the cover open, and then with the
cover closed. The difference between these two measurements shows the required
attenuation values.

Measuring emissions in large equipment or complex systems
Test objects which are too big to be transported to an EMC measuring facility or
are only capable to being installed or assembled at their final destination, can not
be measured by an standard-compliant method. Nevertheless these objects are still
subject to EMC regulations. The only way of assessing any identified interference
emitted by the test object is by comparing levels with reliable values for a reference
radiation source such as the RSQ-3200 and then computing the "true " values for
the test object. The accuracy that can be achieved is comparable with results in an
measuring laboratory.

Checking the accuracy of a measurement receiver or spectrum analyzer
The RSQ-3200 can be used for a wide variety of tests thanks to the huge calibrated
frequency range of its generator (from 100 kHz to 3.2 GHz). The broad frequency
range that is available makes it possible to test almost any frequency. In practise,
all that is needed is a precision attenuator to adjust the VSQ`s output level to the
dynamic range of the test object.
