Description:
This command sets the number of sample points in a data block that are collected
before the MEAS_DONE or BLOCK_READY bits in the status register are set. (See
[SENSE:]SWEep:MODE to see how these status bits are set.) The relationship
between the number of sample points in a block and the size in bytes of the block
can be calculated using the table below:

The legal values for the number of samples increases in powers of 2 from the
minimum number of samples (for example: 4, 8, 16, 32, 64, 128...). If the number
requested is between two legal values, the higher legal value is set.
Specifying a number less than the minimum results in the number of samples being
set to the minimum. Specifying a number larger than the amount the FIFO will
support results in the number of samples being set to the largest value for which the
data will fit in the FIFO.
