Dear Support team,
Per the spec of AWR1843, it's Max I/F is 10 MHz and Max sampling rate is 12.5 Msps (complex).
I'm wondering why these two numbers are not identical. The sampling rate 12.5 Msps (complex) can sample I/F up to 12.5 MHz. But the Max I/F is only 10 MHz which means the sampling rate from 10~12.5 Msps is not usable. If so, why not just write the Max sampling rate to 10 Msps in the spec to avoid misleading?
This in-consistence may cause some trouble. For example, I used sensing estimator to check the max detected range of my config. As you can see, when I set max detectable range to 238m, I got below error
Error 1: Sampling frequency is higher than the maximum sampling frequency (>12.5 Msps)
Error 2: Beat frequency is higher than the maximum I/F frequency (>10 MHz)
But when I simply reduce the max detectable range from 238m to 237m, as you can see the sampling rate becomes valid (<12.5Msps), but the Beat frequency is still higher than the maximum I/F frequency (>10 MHz). However, sensing estimator still reports "No errors are found"
It is obvious sensing estimator checks "sampling rate" first then check "I/F". If "sampling rate" is valid, sensing estimator skips checking "I/F". This might be a bug of sensing estimator but I think the real cause is the in-consistence of "Max I/F" and "Max sampling rate".
