How set sample rate to 30.72Mhz (LTE bandwidth 20MHz)

#1 · 09/11/2021, 11:10

I'd like to know how record IQ stream data with sample rate of 30.72Mhz for LTE bandwidth 20MHz.

Thanks.

Sorry, i dont get your point. Simply record it with the File Writer block.

I didn't expressed correct the question.

The correct question is: how ensure the Sampling Frequency for LTE Channel Bandwidth 20MHz will be 30.72MHz in Spectran V6.

You can adapt the sampling frequency as you like within the SPECTRAN V6 block or the IQ Power Spectrum down to 10ns resolution.

I still don't get the point.

The point is: I don't understand the connection between Sampling Frequency of 30.72MHz and IQ Rate / Receiver clock of 92MHz.
