Hello,
This is an interesting problem. The gate frequency is affecting the number read? Let=92s see if we can figure this out. If you could let me know the answers to the following questions, I bet we can get this solved. 1.)=09What version of NI-DAQ and LabVIEW are you using? 2.)=09Are you setting the Internal Buffer Size using the Counter Buffer (NI-TIO).vi? If so, what are you setting it to? 3.)=09Does the system work if you explicitly set the counts to read? 4.)=09As a general rule of thumb I would set the counts to read to be half of the buffer size. And the buffer size should be big enough to hold AT LEAST two tenths of a seconds worth of data. Does using these rules help? Try these suggestions out and let me know. Also, have you tried using an example program? Does it work? If not, where does it fail? Best regards, Justin T. National Instruments
