sine sweept wave output DAQMx(PXI-4461)

i want generate the sine sweep signal and send this output through PXI4461,

.(the in built sine sweep function of sound and vibration toolkit is not smooth sweep )

the inputs for sine sweep generation are low frequency ,highest frequency of sweep time to sweep, sweep type(Log or Linear sweep rate ) and last Sweep rate.

I can generate this function in Labview with hardware ,but i canot through it with 4461 hardware ,

kindly help me.

 

 

thanks to all,

thanks for help,

 

i wanted to generate sine sweep signal with formula given below,

Y(t)=sin{(2*pi*[(1/2)*(f2-f1)/t2)*t+f1]*t}

where f2 is final frequency,

f1 is lowest frequency,

t1 starting time t2 ending time,

t  elapsed time.

 above sine sweep

for the above equation i want to generate the out put signal and also read that signal throug above harware.

the sampling frequency i have taken is f2*10.

the data of N =1024,

 any suggestion welcome ,

 

thank you .
