LeCroy wavesurfer acquisition loop slowdown

[medvedjohndoe77]

Hello,

I am trying to acquire waveforms from a wavesurfer 434 over ethernet, and I am running into a problem where the scope triggers and then displays a "Processing... " message for multiple seconds before the scope is ready to trigger again. Timeout errors occur even though I am feeding the scope a 10Hz signal (the timeout is set to 10 seconds). This only happens once every 2-3 triggers, and I do not have any of the math, measure, or averaging features enabled on the scope, so I am not sure what is being processed. When I do not have the VI running, this does not occur in either normal or single trigger mode (ie, this does not occur if I manually press the "single" trigger button on the scope multiple times).

More information:

- I am using the example vi, "LeCroy Wave Series Acquire Waveform In Loop.vi," from the 3.2 revision of the driver package and have not modified it.

Thank you in advance for any tips/suggestions.

How is DAQmx related to the question?

Hi,

Which is the Sample Rate (Sample Points) on the scope settings?

At what Timebase do you acquire the 10Hz signal?

Maybe these cause the VI to timeout
