Set the A/D acquisition parameters by issuing commands from the PC or host, and then trigger the command to start A/D data acquisition.

The speed of A/D acquisition is controlled by the clock or timer inside the module.

The speed and number of data collected by A/D are controlled by external electrical signals. The positive or negative edge of each electrical signal triggers an A/D acquisition.

Set the A/D acquisition parameters by issuing commands from the PC or host, and then start A/D data acquisition after being triggered by external electrical signals ( (triggering the electrical signal is the falling/Rising edge trigger)

External digital signal trigger mode can be divided into

1. Pre-Trigger

Before receiving the trigger signal, A/D data will be collected and temporarily stored in the module's memory. When the trigger signal is received, the collected A/D data are transmitted.

2. Post-Trigger

Once the trigger signal is received, A/D acquisition of data samples begins.

3. Delay-Trigger

After receiving the trigger signal, there will be a delay before starting the A/D data acquisition.

4. Middle- Trigger

Before receiving the trigger signal, A/D data has been collected and temporarily stored in the module's memory. When the trigger signal is received, A/D data acquisition is still performed. The amount of data before the trigger signal and the amount of data after the trigger signal are half of the total data. After the collection is completed, the collected data will be transmitted.

1. Above High:The signal is triggered above the high level setting

2. Below Low:The signal is triggered below the low level setting

3. Leave-region :Trigger when the signal leaves the high and low level region

4. Entry-region :Trigger when the signal enters the high and low level region
