3.3 Triggered simultaneous acquisition and
readout (TSR)
Overview
The purpose of the TSR option is to acquire in multi-record mode and read the data simultaneously.
This solution allows longer acquisition duration compare with standard acquisition (DGT) and is
dedicated to applications requiring no trigger loss.
TSR option is not supported in association peak detection (PKD) mode.
TSR and AVG modes can be combined. See
Averager with triggered simultaneous acquisition and
readout (AVG/TSR/INT option) (page 53)
section for details.
Functional description
Standard acquisition and readout vs. TSR mode
In a
standard multi-record acquisition and readout
the duration of the acquisition is limited by the
ADC card internal buffer memory size. The readout of the data is performed after the acquisition has
stopped. The acquisition data rate supported is up to the maximum allowed by the ADC card.
With the
triggered simultaneous acquisition and readout
(TSR), the readout of the data is
performed during the acquisition. The readout can be performed as soon as a programmable number of
records is acquired.
Each segment is triggered by an external or software trigger. Unlike
acquisition and Readout (CSR) (page 40)
mode, this mode allows gaps in the acquisition.
