Reading Out Measured Result
Reading Out Measured Result
Reading out results of several measurements in batch (using data
buffer)
You can use the data buffer to temporarily store the results of several measurements and
then later read out these results in batch.
Data buffer types
There are three types of data buffers (buffers 1–3). Buffers 1 and 2 have the same function.
Buffer 3 has a different function as shown in the below table.
Maximum number of measurements
that can be fed
When the
comparator
function is OFF
Data to be fed
for each
measurement
When the
comparator
function is ON
*1.Use the :DATA:FEED:BUF1 command on page 194 to select the parameter to store
into the buffer from the primary or secondary parameters.
*2.When the comparator function is OFF, 11 is read out.
Feed position
Data fed into the buffer is stored sequentially in the order of measurement. When the data
is read out, the feed position returns to the beginning of the buffer and storage newly starts
from the position of the first data set
The feed position also returns to the beginning of the buffer in the following case:
