Local oscillator frequency sweep for ad9361 Transciever

Thread Summary

The user is working on sweeping the AD9361's LO frequency from 70 MHz to 6 GHz and has encountered a frequency mismatch when visualizing the sweep on an IIO oscilloscope. The final answer suggests that the oscilloscope fetches the LO frequency only once and does not update in real-time, causing the mismatch. The user is advised to use a spectrum analyzer or Python for visualization to ensure the LO is sweeping correctly. The user also seeks to minimize the sweep time to 200 ms with a 50 kHz step size and 1 microsecond delay, but is limited by the spectrum analyzer's capability to visualize fast signals.

Hey I need guidance on ad9361 Lo frequency sweep. To elaborate my query I have divided it into several sections as follows;

What I am doing

Currently I am working  to sweep the Local oscillator frequency of ad9361 over the range of 70Mhz to 6Ghz.

reference 

For this I am using the  spectrum_analyzer.c code as reference. I have also gone through UG570 and UG671.

Objective 

My ultimate objective is to sweep the frequency over this full wide range with the help of c code or in Verilog on ad9361. 

I need guidance to reach my objective. Despite going through the documents I have mentioned above, I am still not getting enough clarity on how to do it. Any kind of help would be appreciated! 

Thankx
