Hello,
we design our own board with 4 AWR2243 (ES1.0) chips in cascade.
To analyse the quality of the tx signal, we set contious mode with the function
rlSetContModeConfigand
rlEnableContMode.
In the spectrum we can see a 40MHz signal overlapped with tx output signal. We assume that the 40MHz signal comes from the quartz crystal "XTAL".
We see this effect on all tx-antennas and in the complete frequency range (76-81GHz).
Have anyone see this effect also on the ESM evalution board?
Hope anyone can give a feedback
