Record 2nd Frequency Right After the First (Without Spill of Data Between the Two)

Hello.  I am attempting to record data from a certain FM frequency right after recording data from a different frequency.  I have attempted such a feat

but looking at the amplitudes of the retrieved data it seems that the data from the first frequency is spilling in to the data for the second frequency.  My guess is that it is taking the USRP longer to change frequencies than it takes for the new data to start rolling in.  A screenshot of my .gvi is posted below.  A screenshot showing graphs of the recorded data is also below.

Any ideas on how to fix the data bleeding?

Hi Fundeedoodle

 

Which USRP are you working with?

I am a bit confused by your question, by "RF Bleeding" do you mean how a but if the signal in the first line are inside the second graph where the amplitude gets larger?

best,
Chase

Hello,

I am working with the NI USRP-2920.  When I refer to "RF" Bleeding, I mean that the data in file two contains both 95.1MHz and 99.9MHz data, when it should only contain 99.9MHz data.  The 95.1MHz signal is much weaker where I am located, so I am basing everything off of where the amplitude gets larger, yes.

Does calling USRP Abort between the first reading and the configuration change the behavior?
