The Signal analysis functions of the DIAdem-CAL can not use.

[Cediland]

I use a DT3003 board for Data Acquisition in my system. My data is signal of Electromyography,and it needs the DIAdem-CALC "Signal Analysis" such as FFT.But these functions in my DIAdem are disable, Why?

Cediland,

Which edition of DIAdem do you have? The Starter Kit does not come with FFT functions, while the Standard Edition does. You can upgrade your edition to the standard kit which also includes SQL/ODBC connectivity, Curve Fitting, VIEW, and Scripting via AUTO.

Mr.Gerardo Garcia:
The Edition we use is "DIAdem Starter Kit with DAC Bundle", which were bought in Germany by my boss.How can we upgrade to the Stander Edition?And How much will it cost?
Do you think my data of electromyograhy signal needs FFT?(the sample is provided when I requested you help yesterday).

Cediland,

I don't know much about EMG signals, but the basic question is whether you need to do frequency analysis? FFT converts a signal from the time domain to the frequency domain.

I forgot to mention that if you need to upgrade you can contact your local NI office. Visit them at ni.com/germany.

Yes!
We do need Frequency Analysis.The EMG is some kind of time-voltage signal.DIAdem do us great help in data sampling.We need to get information such as Average Amplitude, spectral parameters like Mean Power Frequency,Median Frequency from the raw EMG. Is "Signal Analysis" function of the DIAdem standar version able to full fill our demands?

Re:Thanks for your advice again.Your helps are important for us.
