frequency measurement off by a factor of e6

[livermor]

I am using a niScope Read WDT to acquire statistical measurements of the frequency. However, when I record the frequency, it is off by a factor of 10MHz. That is, if I input 5MHz or 1MHz, it gives me the result as 0,1Hz and 0,499999Hz. Any ideas why?

Please see attached vi and measurement file.

My quick guess would be the locale setting for Windows. You appear to be using a European separator (comma).

I Don't have LV2010 installed or an niScope, but I suspect that there must be a place to change the separator setting for locale on one of the the VIs or in NI-MAX.

You didn't include your analyze VI in your ZIP.

Oh, right. Here it is 🙂

My guess is that your global is the cause of your problems.  You are coercing your captured data to a waveform that only supports an array of DBLs.  No timing info is saved in your global.  This would cause the analysis VIs to not be able to report correct timing/frequency info.

You also don't need your global.  You have the two subVIs right there.  Create a control on your analyze VI and wire the two VIs together.
