How to configure the dac to interpolating mode?

Hi jerry,

I have the following queries

 

1.In the Example I hav tried to insert the baseband FSK modulator which gives IQ data out. So please tell me how to convert to the 32bit data as given in the example.

 

2. You said that the NI 5640 just resample it but not upconvert it. Why?

But when you see the individual specification of AD9857 it will resample as well as upconvert it. Why the card has this limitaion.

 

3. Where you have configure the PD clock of the AD9857?

 

4. In my application I have generate Baseband digital modulated data at 120KSPS(120KSPS of I and 120KSPS of Q), now this data has to be resampled to 30MMPS(no exactly in around) an the up converted to 8.6MHz. How this can be done on NI 5640r?
