About Trace Data (802.16 OFDMA)

Menu Path: Trace > Data

802.16 OFDMA modulation analysis is supported with a full set of advanced measurement trace data for time domain analysis, frequency domain analysis, and modulation domain analysis. Available trace data includes Main, Search, and Raw Time data, Ch Frequency Response and Differential Ch Frequency Response data, CCDF Complementary Cumulative Distribution Function and PDF 1) Probability Density Function Trace Data, or 2) Portable Document Format (PDF) created by Adobe Systems is an open standard for document exchange. statistical trace data, modulation domain trace data including IQ Meas/Ref constellation diagrams, Error Vector Time, Error Vector Spectrum, Common Pilot Error, Symbol Table, Error Summary Data, and more. 802.16 OFDMA modulation provides the following unique trace data including the Data Burst Info trace data, which is a table of summary data for each Data Burst in the current measurement analysis zone, and additional Error Summary results including Data subchannel RCE Relative Constellation Error is the RMS level of the Error Vector Magnitude, averaged over all subcarriers and all detected OFDM symbols., Pilot RCE, unmodulated RCE, and RSSI Received signal strength indication. For a complete list of available Trace Data, see Available Trace Data.

Using the Color Trace Data Displays

For 802.16 OFDMA, the IQ Meas constellation trace, the Error Vector Spectrum trace, the Error Vector Time trace, and the Symbol Table trace use unique colors to identify and relate common OFDMA symbol data points. Using unique symbol colors makes it easy to visually relate common symbol data points between trace displays. This topic describes how the symbol colors for the stated traces are specified and changed. The zone analysis mode affects how the trace data colors are specified as described below: Also, marker annotation for these symbols will indicate the data burst name as defined in the Zone Definition Grid.
