Hi expert，
As a follow-up to my last question, I thought I'd ask a new question with a link to my last question
I have tried the 100M NCO setting you mentioned, and successfully observed the tx_tready signal and SYNC signal in ILA, but I still don't seem to see any signal on the oscilloscope(I use TXA,and I can guarantee that my oscilloscope can receive signals within 500MHZ),I hope you can answer the following questions.
1.could you please give me some suggestions? (I will post my latte Settings below)
2.In addition, I have a lot of confusion, if I want to send a random number signal, how do I determine my center frequency(Here I'm just repeating an increasing sequence)？
3,Moreover I use the transmission mode of 24410 and only use two lines to transmit signals. Can I use TXD to transmit the signal (maybe I can use SRX6,SRX7 to receive the signal and send it via TXD by setting sysParams.jesdRxLaneMux = [2,3,4,5,6,7,0,1],sysParams.txEnable =[True,True,False,False]?) May I ask if this is feasible?
