3.4 Averager with triggered simultaneous
acquisition and readout (AVG/TSR/INT option)
Overview
The combination of averaging mode and streaming feature (AVG & TSR options) allows signal
acquisition, real time averaging and data readout simultaneously, avoiding trigger loss.
The averager features are the same as with AVG option (max number of average, baseline correction,
max record size, triggering, …)

Real-time averaging (AVG option) (page 20)
.
The addition of simultaneous acquisition and readout feature (TSR) on top of real-time averaging,
enable minimal dead time between accumulations.
Functional description
The architecture is based on TSR (Triggered simultaneous acquisition and readout), and enables
simultaneous real time averaging and transfer of average records to host processor.
Acquisition sequence
As illustrated below, the readout of an "averager record" is performed during the next averager
accumulation The readout can be performed as soon an "averager record" is acquired.

The feature Noise suppress accumulation (NSA) is not supported with AVG+TSR mode.
