decimationFactor The rate at which data is received is high, so retrieving every successive data sample
will likely provide little information (due to memory limitations). The decimation
factor specifies how many successive data samples should be added together and
reported as one data sample. If the decimation factor is not specified, every
successive data sample is reported.
df {0 . . 2^31}
presummationShift If decimationFactor is specified, then successive data samples get added. This can
potentially cause an overflow. The presummationShift value specifies the number of
bits by which the data sample should be right-shifted before being added. Specifying
a presummationShift value will result in less precise individual data samples but
provides a mechanism to analyze the behavior over longer duration of time.
pss (0 . . 32)
print Specifies whether or not the collected values should be printed out when the
collection completes. The default is on.
tone Every burst of signal data contains samples from N frequency tones. This parameter
identifies which of those frequency tones should be used.
circular Implies successive data samples should use successive frequency tones.
average Implies successive data samples should average the burst data over all the N
frequencies and then use that value.
number Specifies that data from a particular frequency in the burst should be reported.

trigger Specifies when the collection has to be stopped. The <threshParam> <threshType>
(antenna_num) parameters uniquely identify a threshold specification. When this
threshold is reached, the timeline will be stopped and the data collected.

in (Interference + Noise) The interference + noise power levels are computed by the
hardware on a burst-by-burst basis.
NoteThis parameter is available for a dual antenna system only.
inr (Interference + Noise Ratio) The ratio of the interference + noise power levels
captured by the first antenna to the second antenna on a burst-by-burst basis. This
value is specified as a log to base 2 number.
