4: Measurement Bitmap
This parameter is a decimal integer, for which the equivalent binary number specifies the set of
measurements to be made during the analysis interval. Each bit in the equivalent binary number
represents one of the available measurements. The selection of a radio standard for the acquisition
determines which measurements are available and which are not, as defined in following table .
The way to determine the appropriate value for the parameter is to select from the available
measurements, and add up their decimal weights (as shown in the rightmost column). For example, to
choose the Occupied BW test (decimal weight 1024) and the Tx Power test (decimal weight 1), set the
parameter value to 1025. This is binary 10000000001, and it selects only those two tests. (This would not
be a possible value in the GSM/EDGE radio standard, which does not support the Occupied BW test.)
NOTE The Basic IQ Data measurement (bitmap value “8”) is incompatible with averaging. If the
Average Count parameter for the acquisition is set to a value greater than 1, the analysis
intervals within that acquisition cannot include Basic IQ Data in the Measurement
Bitmap.
