In OneShot mode, after the AI acquisition triggers, the acquisition device automatically stops the
acquisition after the acquisition reaches the set number of times according to the set sampling speed.
The user program only needs to read the set data amount from the computer memory buffer.
Single point reading
Single point reading refers to the AD conversion of the selected channel and reading its
conversion results.

Sampling rate
There is an independent ADC in each analog input channel of PCI-5000 series data acquisition
device, so all channels can work at the maximum sampling rate at the same time when analog input
is collected
.

Trigger
The PCI-5000 series data acquisition device provides rich trigger options. The schematic diagram of
the AI acquisition trigger options are shown in Figure 3.1.
AiSoftTrig software trigger
DiSoftTrig software trigger
DoSoftTrig software trigger
Global software trigger
Trig_IN external trigger input
AI trigger signal
Figure 3.1 AI trigger options
The AI acquisition uses the AiSoftTrig software trigger as the trigger source by default. The AI
acquisition can use other trigger sources via software settings to achieve the synchronization of each
function.
Software triggering means that the computer sends a command to the acquisition device to achieve
the effect of device triggering.
Trig_IN external trigger means that when Trig_IN receives a rising edge, the device triggers.
Clear trigger
The AI trigger status can be reset to an untriggered state by software settings.
Attention
The set number of collection points cannot exceed 2MPts
