Validation of Table Influence Services

We can perform evaluations of set-up tables, as described in CISPR 16-1-4 (2010) Clause 5.5.2, to determine the influence of a set-up table for the 200 MHz to 18 GHz frequency range and to estimate its related uncertainty contribution to the field strength measurements.

We evaluate the influence of the set-up table by performing two transmission measurements: one with the set-up table present, the second with the set-up table absent. During the two measurements, we keep the transmit antenna in the same specific arrangement. The difference between the measurement results with and without the set-up table gives an estimate of the influence caused by the table.

Following the test, we issue a report which provides our customers with the table value in dB for the following frequency ranges: • 200 MHz to 1 GHz • 1 GHz to 6 GHz • 6 GHz to 18 GHz
