Measurement results
The R&S FSV-K91 determines certain inconsistencies in the signal and informs the
user with an appropriate warning. If the signal was analyzed successfully the results –
indicated by a message - also contribute to the overall analysis results. The corre-
sponding PPDU in the Capture Memory is highlighted by an orange bar.

length estimated from the PPDU power profile
If a required property set by the user in the Demod Settings does not match the corre-
sponding PPDU property from the list, the PPDU is dismissed. An appropriate mes-
sage is provided. The corresponding PPDU in the Capture Memory in not highlighted.
