5.16.3 Power vs Time – Full Burst and Rising/Falling Data

Both measurement results are again simply slightly different views of the same results

data.

All complete bursts within the capture time are analyzed in three master bursts. The

three master bursts relate to the minimum, maximum and average values across all

complete bursts. This data is returned in dBm values on a per sample basis. Each

sample relates to an analysis of each corresponding sample within each processed

burst.

The type of PVT data returned is 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, minimum burst data values

TRACE2 full burst, mean burst data values

TRACE3 full burst, maximum burst data values

If the graphic type selected is "EDGe", then the return data is as follows.

TRACE1 rising edge, minimum burst data values

TRACE2 rising edge, mean burst data values

TRACE3 rising edge, maximum burst data values

TRACE4 falling edge, minimum burst data values

TRACE5 falling edge, mean burst data values

TRACE6 falling edge, maximum burst data values

Supported data formats (see FORMat[:DATA] on page 176): ASCii|REAL

For IEEE 802.11b:

If the graphic type selected is "RISing" or "FALLing", only 3 traces are available (1 to 3)

and represent the minimum, mean and maximum bursts data for the respective graph

selection. The number of samples returned during full burst analysis depends on the

modulation type and is typically 5000.

The number of samples returned when the "Rising and falling" graphic type is selected

is less than what is returned for full burst and is approximately 400 samples. The sam-

ples are returned in floating point format as a single sequence of comma delimited val-

ues.

5.16.4 Spectrum Flatness

Four separate traces are available for these measurements. Trace data for a particular

trace is only obtainable by querying the appropriate trace.
