This time I will not let you down!</div><div>I have been using TestManager in a real industrial hydraulics application for a while now. I generally had good results with it, but now I wish to change my sampling rate and also the accuracy of the data captured (I was using 1000 Hz @ 2 accuracy which is too high). I have tried doing so but I see the following observations about the options that I can set/choose:</div><div>a. the sampling rate cannot be any value I wish to choose for all channels. I tried sampling @ 300, 450, 720 Hz and always TestManager rounds off my value to a different one, <i>a calculated
one</i> I see, so it must implement a formula I do not know about. I would like to sample @ 10 Hz in my application which I see it can handle, but I do not know why an intermediate value for the sample rate is not possible.</div><div>b. The data accuracy I choose is not "recorded" while using the Scope. I tried inputting different values from 1 to 9 and then verifying the .txt files generated by exporting the acquired data in a Matlab format. Most of the time I get values with 16 digits after the "." in the number. Other times I get values with only 2 decimal points. I see the files are a lot larger when having 16 digit accuracy than when I have 2 digit accuracy and I would like to have 4 accuracy, because space is an issue for me.</div><div>c. What is the effect of a high "Buffer Size/s" in the Data Transfer option pane? I already know the effect of having it too small (the graphics of the signals are limited), but I would like to know what is
the drawback of having it too large? One thing I notice is the Data Rate going very high. What is an optimal value for that to input?</div><div>My Data Rate I read here right now is 70-80 Kb/s @ 300 Hz. Does this have an effect on the topics I've written so far?</div><div><br></div><div>I would like to thank you! For everything!</div><div>Kind regards,</div><div>Alex Marton</div><div><br></div><div><br></div><div style=""></div> </div><div style="position:fixed"></div><div></div><div></div><div></div></div><br>
