Hi Ken,
Just to follow up with your comments about the one-shot trigger mode... was this feature ever implemented for the TSW14J56? I'm using this paired with a DAC38RF82EVM board, and would also like to operate the DAC in one-shot mode. I tried to work with the preamble mode, but maybe I don't understand the intended operation. I created an external pattern file with a 1024 sample waveform: the first 512 samples define the waveform I want to one-shot, and the last 512 samples are all zeros. From my reading of your comments and the HSDC Pro manual (SLWU087D.pdf), I'm assuming the preamble value sets the starting point for the data you wish to "loop". So I set the preamble=512, assuming that a single click to the "Generate Trigger" button on the HSDC Pro would output the first 512 samples in my external pattern file a single time, then "loop" the last 512 samples (all zeroes) until the next trigger. The output of this experiment did not match expectations, to say the least. The DAC continues to loop all 1024 samples, albeit in a very irregular (jittery) fashion. One click of the "Generate Trigger" button creates the expected waveform, a subsequent click generates something very different.
When I operate the HSDC Pro software in the standard looping/ "Send" mode, I am able to trigger off my desired waveform, in a fairly stable manner.
Any suggestions for how to realize the ideal, triggered "one-shot" pulse output?
Much thanks in advance,
Steve Krupa
