Sampling And Data Acquisition - Acqiris U5303A User Manual

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 U5303A 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. The
maximum sampling rate shown above is achieved by combining the two channels.

The External Clock can be used to vary the sampling rate of the ADC card, see

Combining channels (Interleaving -INT option)
When ordered with -INT option, the U5303A ADC card supports the capability of combining the
converters (and their memories) from two channels to analyze a single input channel. With this feature
the maximum sampling rate and the maximum amount of acquisition memory are doubled.
