Hello,
We are working on AFE7950evm. We are able to update Rx NCOs of all the channels from 9500 MHz to 11500 MHz . But we are not able to update to any frequency outside this range. For example, updating Rx NCO to frequencies 9000 MHz, 12000 MHz, are not working.
Looking for your help.
Thankyou.
Hello,
Are you using ADC sample rate of 3000MSPS? If so, you can not use NCO at 9000MHz or 12000MHz as this is a Nyquist boundary. Can you send the error you get when you try other NCO frequencies?
Regards,
Vijay
Hello,
We dont get any errors. And also we are not particularly interested in frequencies 9000 and 12000.
Frequencies less than 9500 and greater than 11500 are not working. Like 9400, 9300, 11600, 11700 etc.
With not working I meant we cant see output signal on signal analyzer.
Im not able to find a way to attach scripts that we run. Could you suggest a way ?
Thankyou.
Hi Thameem,
I will reach out to you through email to share your scripts and further discuss this issue.
