Adjacent Channel Power—Number of Measured Points

[:SENSe]:ACP:POINts <integer>

[:SENSe]:ACP:POINts?

Selects the number of data points used to measure the reference (carrier) channel. The automatic mode chooses the optimum number of points for the fastest measurement time with acceptable repeatability. The minimum number of points that could be used is determined by the sweep time and the sampling rate.

You can increase the length of the measured time record (capture more of the burst) by increasing the number of points, but the measurement will take longer. Use [:SENSe]:ACP:OFFSet:LIST:POINts to set the number of points used for measuring the offset channels.
