3.3 Averager with simultaneous acquisition and
readout (AVG & CST)
Overview
The combination of averaging mode and streaming feature (AVG & CST options) allows signal
acquisition, real-time averaging and data readout simultaneously, avoiding trigger loss.
The features specific to the averager mode are the same (maximum number of average, baseline
correction, max record size, triggering, …) — see detail in section
The addition of simultaneous acquisition and readout feature (CST) on top of real-time averaging,
enables minimal dead time between accumulations.
Functional description
The architecture is based on simultaneous acquisition and readout (CST), and enables simultaneous
real-time averaging and transfer of accumulated records to host processor.
Acquisition sequence
As illustrated below, the successive records of a sequence are accumulated. The readout of the
resulting "accumulation record" is performed during the next averager accumulation. The readout can
be performed as soon an "accumulation record" is acquired.
