Hello Fausto,
Thank you for your answer.
I am afraid that polling a digital input to trigger a software trigger for the conversion will be too slow for my application.
This is because I have to measure the peak voltage of fast pulse (~10µs) at the output of a peak and hold circuit.
In other words in need to acquire the signal very shortly after the TTL signal rising edge. Is that possible using the DT9816? In all honesty I may have chosen the wrong device for my application.
Wouldn't it be possible to use the continuous scan mode, trigger the scan start with the Ext trigger while using a buffer a small size?
Thanks in advance.
Regards,
Gary
