Decimation
Option Decimation refers to discarding a portion of the data in the display buffer when
it fills. Each option controls the flow of data through the display buffer in a
unique way, and creates a corresponding type of display on the plot.
Each option follows the same general process:
• The buffer fills with data
• The data is decimated (reduced) according to the option selected
• The retained data is shifted to the front of the buffer to form a contiguous
block
• The process is repeated
Every Other Point—This option causes the buffer to accept acquired data
until it fills, perform a decimation of every other point, shift data, and repeat.
This option decreases the resolution of the initial data as a function of the
number of times the buffer fills.
First pass: When the buffer fills for the first time, it accepts every point of
acquired data until the buffer is full, then performs a decimation by discarding
every other point in the buffer. The retained points are shifted to the front of the
buffer to form a contiguous block, leaving the back half of the buffer empty
and ready to receive new data.
Second pass: The buffer fills the second time as before until full, then performs
another decimation and data shift.
Subsequent passes: The process is repeated in subsequent passes in the same
way until stopped.
