The quality of digital modulation of RF interface during absorption stress can be tested via
RSA5000N VSA (see figure 16). Here it is possible to display also I and Q stream separately
to see which part of transmitter is affected by the interference. Additionally a BER test could
be performed during stress situation.
Additionally, with the vector network analyzer function [VNA] it is possible to measure out
related antennas or other components to see if a possible degradation of performance is
visible (see figure 17).
