– Spectrum FFT (see Spectrum FFT softkey)
– Constellation vs Symbol (see Constell vs Symbol/Carrier softkey)
– Constellation vs Carrier (IEEE 802.16–2004 OFDM only, see Constell vs Symbol/Carrier
softkey)
– Conditional Cumulative Distribution Function (see CCDF softkey)
– Bit Stream (see Bitstream softkey)
• frequency sweep measurements

For current restrictions refer to Current restrictions to the IEEE 802.16e–2005 OFDMA/WiBro signal to
be analyzed.
The measurement result display is divided into two panes:
• Measurement settings
• Result displays
The results can be displayed in form of a list or a graph (see also Display List/Graph softkey).
– Result summary list
– Result display graph
Current restrictions to the IEEE 802.16e–2005 OFDMA/WiBro signal to be analyzed
• standard
– IEEE 16–2004/Cor1–2005, IEEE 802.16e–2005, OFDMA Physical Layer Mode, 1 October
2004/28 February 2006
– IEEE 16–2004/Cor1–2005, IEEE 802.16e–2005 based WiBro
• FFT sizes
The FFT sizes 128, 512, 1024 and 2048 are supported.
• subframes
– Either a DL subframe or a UL subframe can be analyzed at one point in time.
– One DL–PUSC zone per DL subframe is supported.
– One DL–FUSC zone immediately following the first mandatory DL–PUSC zone is supported
(DL subframe).
– One UL–PUSC zone per UL subframe is supported.
– The subframes have to be separated by sufficient power off gaps.
• segments
The first mandatory DL–PUSC zone must contain exclusively one segment. The assignment of
subchannel groups to this segment is not restricted.
• symbols
The signal to be analyzed must contain at least two OFDMA data symbols. More OFDMA data
symbols will improve the accuracy of the measurement results.
