salvai.m

Hi,

I have a problem with my app.exe build.

I attach a simple code; the Vi open and close a TDM file.

If I run this Vi in Labview works fine.

If I build the application.exe on a notebook and I run it I got "Application crash with error ntdll.dll 00018fea".

I've tried to build the Vi on another Pc Desktop with Labview and here if I run the exe it works fine.

On the two PC I have LV8.5; the build options are the same.

On the notebook I've try also to reinstall LV8.5 but I got the same error.

Can you help me?

Thanks a lot

Hi guys,

in my program I acquire continous data with PXI-4472 and DAQmx (fs:40960Hz, 4096 samples).

I run this on two PC, one dual-core, the other one-core.

Sometimes on the dual-core PC, the acquisition seems "paused" and it "restart" after 5sec but the buffer could go on overflow. In these 5 sec on the task manager I saw one of the two core works at the 100%.

On the other PC one-core the program always works fine.

(I've got this problem also on a notebook dual-core with a 4472 Simulated device)

Someone of you got also this problem ??? and better someone can help me ?

Thanks a lot !!!

hi

in my application I need to apply an A-weighting filter to my microphone signal; sincerly I don't want to buy S&V toolkit only for this function...

about you is possible doing it other way ???

I know that the transfer function (http://en.wikipedia.org/wiki/A-weighting) in the Laplace domain but I don't know how to apply it.

Thanks a lot !!!

Hi Luois, first thank you for the reply.

I'm using a 6070 multifunction board.

I acquire packet of 4100 samples;

Sampling rate: 500000 s/sec;

Scan rate: 41000 s/sec;

I use DIAdem DAC to acquire and analyze.

I'm not sure of this parameters also because I've see that if I change some of them the freq of the pulse change...

Thank you

Hi,

when I acquire a signal AC of my phonometer and I do a FFT I obtain a pulse of 80dB at 13600 Hz without noise in the room; the same problem succed when I disconnect the cable in input....So I think it's an electric noise...do you know which can be the source of this noise ??

Thank YOU
