4.1 Sampling rate reduction (binary decimation)
A programmable binary decimation may be used to lower the sample rate by a ratio of 2
n
,
where
n
is defined in the range of 1 to 10, depending on the model and configuration (See Table below).
To enable decimation, user should set the sampling rate to required decimated sampling rate.

The accuracy of absolute trigger time is guaranteed (as specified in the U5303A
) down to
sample rates 1/16 of the highest sample rate (1/32 of the highest sample rate with interleaving).
