データコンバータープロSW about the Trigger Modes in the High Speed Data Converter Pro GUI

Hi

When you use HSDC PRO with either the TSW14J56 or TSW14J57 EVM, there are trigger ports (both input of the trigger or output of the trigger) such that you can trigger an ADC capture from an external trigger signal or you can trigger a synchronous DAC output based on trigger signal.

see section 3.1.3.2 of the below documentation for detail:

Hello,

When you capture with an external trigger for the ADC data, the data is "stored" in the TSW14J56 memory until you instruct the HSDC PRO to release the memory. Therefore, the interval is limited by the storage and instruct to release memory.

Ryota-san,

All the HSDC PRO automation are located in:

C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\HSDCPro Automation DLL

There should be trigger release in the DLL.

The 2ms and 8ms interval may be limited by your DLL run time. 

For such accurate trigger system, it is best that you create your own FPGA solution to perform such activity. 

Hi

It will be very difficult as you will need to dump out the data before each trigger to ensure the next trigger captures
