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,

Hello,
Can you tell us what is the problem you are facing in generating the output through 4461 card.

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 .
