1.3 Sampling and data acquisition
The ADC card acquires waveforms in association with triggers. Each waveform is made of a series
of measured voltage values (sample points) coming from the ADC at a uniform sampling rate.
Sampling rate
The SA240P acquisition card contains an analog-to-digital conversion (ADC) system that can
sample waveforms, in a real time sampling mode, at the maximum rates shown in the table below.
