What is the SFDR of the AD9361/4 Devices
We do not have any measured results or spec for SFDR of device. It depends on the way gain gets set if AGC or is set if MGC is used for a particular condition and needs to be tested and verified by customer.
Can I real time get the RX gain through SPI interface? When I use AGC. So I can use the RX gain data to calibartation my digital data output? Am I right?
There are control outputs which can be monitored for real time applications.
You can set register 0x35 - 0x16 for CH1 and 0x17 for CH2 to get the gain index for full gain table mode only.
for more details refer UG-570 control output section
In my application I want to monitor TWO RX channel gain at the same time.I'll find anathor way to deal with it.Thanks a lot.
SPI will not be real time . For your requirement , you can go for MGC, Manual gain control and use Control out pins to move the gain indices.
Please refer UG-570 Section on MGC OVERVIEW. (page 38)
