Hi All,
I am just trying to get a feel if Dasylab will allow the generation of a vibration signal analyser module that can be used in the field as a replacement to a dedicated dual channel vibration analyser instrument for modal testing etc. I have had a bit of a look at the software and it appears it is capable of doing all the 'maths' it needs to (fft's, transfer functions etc) and will plot what I want. My concern lies with the 'field usability' and control of any such module. In such an application you don't want to be required to edit module properties directly, these need to be selectable on a clear User Interface setup page, things like window size for fft (i.e.. 50Hz, 100Hz ... 1000Hz etc) , number of spectral lines (i.e.. 400, 800 etc) window type (Hanning, rectangular etc), trigger types, number of averages to take, option to accept reject averages etc etc.
Some of these parameters will be program control variables others will be specific module inputs.
From what I have seen some of these can only be changed directly from within the particular module, e.g.. window type in the window function. Is there any way to port these module control options from with in the various modules to a single user input window, such that a seamless "Operator friendly' instrument can be deployed that doesn't require on site programming in dasylab?
Would also welcome any examples, including how to control such a program with respect to triggering, accumulating required (user selectable) number of averages etc.
Basically I just want a good old fashion 2 or 4 channel vibration spectrum analyser but updated to run on a tablet pc with a USB input module. The key for me is the ease of use / control once in the field. Need to know if Dasylab can do the job.
thanks in advance to all/any who respond.
