AI while frequency sweeping.

I intend to get the data (DAQ) while frequency sweeping (PXI-5421).

 

I used a continuous analog input routine followed by 1MHz timing DAQ function for this work.

Set frequency -> DAQ Read -> buffer check -> next frequency -> Read -> buffer check..

The delay time of each iteration is around 50 ms ~ 100 ms.

 

I found the buffer was not clean just after DAQ read (under the automatic /manual number of samples).

 

How can I ensure the DAQ read was done in only a single frequency (synchronize problem?)?

Is there some methods to stop to fill buffering when I set a frequency? maybe, then, start buffering is okay to this question.

 

Best,

 

Labmaster.
