– Spectrum Flatness Difference (IEEE 802.16e–2005 OFDMA/WiBro)
This result display shows the absolute difference of adjacent carriers. The limit lines are
displayed according to the requirements of the standard. The minimum, mean, and maximum
statistics is performed over the analyzed zones in the capture buffer.

Spectrum Mask (IEEE 802.16e–2005 WiBro)
Sets the Spectrum (Emission) Mask result display. For the IEEE 802.16–2004 OFDM, IEEE
802.16e–2005 OFDMA standards, the result is displayed in graphical form (Display Graph
selected), or in tabular form (Display List 1/2 selected). For the IEEE 802.16e–2005 WiBro
standard, graph and table are displayed combined.
This result display shows power against frequency. A limit line representing the spectrum mask
specified for the selected standard is displayed and an overall pass/fail status is displayed for
the obtained results against this limit line.
For the IEEE 802.16–2004 OFDM, IEEE 802.16e–2005 OFDMA standards, the span of the
results is related to the specified sample rate.
For the IEEE 802.16e–2005 WiBro standard, the table contains the results for each of the
individual frequency ranges. On the trace, the highest power value is marked for each of the
specified frequency ranges with a marker.
The number of sweeps is set in the General Settings dialog box, Sweep Count field. If the
measurement is performed over multiple sweeps both a max hold trace and an average trace
are displayed. For the IEEE 802.16e–2005 WiBro standard, the Spectrum Emission Mask
measurement is configured via the SEM Settings softkey.
