R&S <strong>ZVL</strong>-<strong>K1</strong> WiMAX, WiBro Measurements (Option K93)<br />

Each OFDMA symbol of a zone must contain at least one active burst, i.e. each OFDMA symbol of<br />

<strong>the</strong> zone must comprise subchannels belonging to an active burst. The zone/segment must be<br />

covered by active bursts, i.e. no gaps at <strong>the</strong> beginning, mid or end of <strong>the</strong> zone/segment are<br />

allowed.<br />

UL subframes<br />

In case of UL subframe analysis, <strong>the</strong> frame number must be constant <strong>for</strong> <strong>the</strong> signal to be analyzed.<br />

Measurement settings<br />

The overall measurement settings used to obtain <strong>the</strong> current measurement results are displayed below<br />

<strong>the</strong> title bar (see Fig. 3-46). The following settings are listed:<br />

Setting Description Standard restrictions<br />

Frequency The frequency of <strong>the</strong> measured input signal.<br />

Burst Type The type of burst being analyzed IEEE 802.16–2004 OFDM only<br />

Zone/Seg The zone and segment being analyzed IEEE 802.16e–2005 OFDMA/WiBro only<br />

Signal Level The expected mean signal level <strong>for</strong> <strong>the</strong> input signal.<br />

Modulation Shows <strong>the</strong> active setting selected in <strong>the</strong> Demod<br />

Settings dialog box, Demodulator list.<br />

If <strong>the</strong> Mod. Detection field is set to ALL, ALL is<br />

displayed.<br />

Shows <strong>the</strong> active setting selected in <strong>the</strong> Demod<br />

Settings dialog box, Demodulator list.<br />

If <strong>the</strong> Modulation Analysis Scope field is set to ALL,<br />

ALL is displayed.<br />

External Att The attenuation (positive values) or gain (negative<br />

values) applied to <strong>the</strong> signal externally (i.e. be<strong>for</strong>e <strong>the</strong><br />

RF or IQ connector of <strong>the</strong> spectrum analyzer), e.g.:<br />

External Att = 10 dB means that be<strong>for</strong>e <strong>the</strong> RF<br />

connector of <strong>the</strong> R&S <strong>ZVL</strong>-<strong>K1</strong> a 10 dB attenuator is<br />

used<br />

External Att = –20 dB means that be<strong>for</strong>e <strong>the</strong> RF<br />

connector of <strong>the</strong> R&S <strong>ZVL</strong>-<strong>K1</strong> a amplifier with 20 dB<br />

gain is used.<br />

Data Symbols Shows <strong>the</strong> minimum and maximum number of data<br />

symbols that a burst may have to be considered in<br />

results analysis .<br />

Zone Offset/Length A combined display of <strong>the</strong> offset and length of <strong>the</strong><br />

analyzed zone<br />
