dynamic range for each partial measurement. In addition, the desired frequency resolution
(usually RBW/2 and sometimes RBW/4) is easily achieved in a TR. The SA fulfils the most of
CISPR 16.1 requirements and the results are a very good approximation, which is absolutely
sufficient to perform pre-compliance tests. A TR fulfills CISPR 16.1 for 100% and can also be
used for compliance tests. RIGOL´s new EMI solution in the RSA5000N / RSA3000N
compensates most of the disadvantages with the scan table. The most used frequency ranges
inclusive the correct 6 dB RBW filter for EMC tests are pre-defined in 10 individual ranges
(see figure 2). All pre-defined settings can be modified / stored according to the own need.
In order to compensate these disadvantages in a SA, the EMI solution of RIGOL stores the
basic setting of the most important frequency bands, including the 6 dB RBW required, in a
scan table in advance (see figure 2) in individual areas [Ranges]. All parameters can be
adjusted separately per area according to your own wishes.
For example, it is possible to use up to 10,000 measurement points per area. The basic
settings of measurement points refer to a frequency resolution of RBW/2. For a higher
resolution, different ranges can be combined for one test. With a combination of e.g. 3 ranges
it is possible to use 30.000 measurement points over the whole frequency to reach expected
resolution if necessary. The integrated pre-amplifier (option) and internal attenuator (0 to
50 dB) can be varied per range as well. With combination of different ranges it is possible to
increase the dynamic range of the complete measurement without interrupting the
measurement itself, because the dynamic range can be adjusted for each single range. The
disadvantage of frequency resolution and dynamic range in an SA can be compensated in EMI
mode. Additionally to the standard 3 dB RBW filter, the EMI solution contents also the
