R&S FSL TRACe Subsystem (WiMAX, K92/K93)

Constellation vs Carrier
This measurement represents I and Q data. Data will be returned as a repeating array of interleaved I
and Q data in groups of 53 channels including the channel 0, until all the data is exhausted.
Each I and Q point will be returned in floating point format. TRACE1 is used for this measurement results.
Power vs Time – Full Burst and Start / End Data
This description applies to measurement results from the IEEE 802.16–2004 OFDM standard.
Both measurement results are once again simply slightly different views of the same results data.
All fully complete bursts within the capture time are analyzed. This data is returned in dBm values on a
per sample basis. Each sample will in some way relate to an analysis of each corresponding sample
within each processed burst.
The type of PVT data returned will be determined by the TRACE number passed as an argument to the
SCPI command, in addition to the graphic type that is selected.
If the graphic type selected is full burst, then the return data is as follows.
TRACE1 full burst, burst data values
If the graphic type selected is rising/falling, then the return data is as follows.
TRACE1 start, burst data values
TRACE2 end, burst data values
The number of samples returned during full burst analysis will depend on the modulation type and will
typically be 5000.
The number of samples returned when the rising and falling graphic type is selected will be less than
what is returned for full burst and will be approximately 400 samples. The samples will be returned in
floating point format as a single sequence of comma delimited values.
Power vs Time – Full Subframe and Rising/Falling Subframe
This description applies to measurement results from the IEEE 802.16e–2005 standard.
Both measurement results are once again simply slightly different views of the same results data.
All fully complete frames within the capture time are analyzed into three master frames. The three
master frames relate to the minimum, maximum and average values across all complete frames. This
data is returned in dBm values on a per sample basis. Each sample will in some way relate to an
analysis of each corresponding sample within each processed frame.
The type of PVT data returned will be determined by the TRACE number passed as an argument to the
SCPI command, in addition to the graphic type that is selected.
If the graphic type selected is full burst, then the return data is as follows.
TRACE1 full subframe, minimum frame data values
TRACE2 full subframe, mean frame data values
TRACE3 full subframe, maximum frame data values
