Part Number:AWR1642
Hi,
With the below setup, test on AWR1642 EVM.
start frequency=77GHz,
slop=0 MHZ/us
Rx input is connected to a mixer at 73.6GHz, the expected IF frequency is 77-73.6=3.4GHz
My customer tested in two methods, below figure 1 show the test result in radar studio 0.6.1.1, the signal is very good; figure 2 show the result in mmw demo SDK 1.0, the result is very bad. Compared the below two figures we can find in the figure2 IF signal the phase noise is bigger, and there is one strange band signal label with red circle. Could u pls help give any comments on what would impact the signal quality?
Suggest u can test it at your side just use the mmw demo in SDK 1.0 on awr1642 EVM, set slop=0 to get the IF signal.
Figure1 Result in Radar studio
Figure2 Result in mmw demo SDK 1.0
