|

|
* - RF bandwidths of both TX and RX are expanded to the current sample rate. It can be changed after calibration without effecting phase synchronization.
|
||||||
|
* - DDSs are enabled and left on after synchronization. Changing these DDSs or switching to DMA sources will not effect phase synchronization.
|
||||||
|
* - TX and RX LOs are set to the same frequency based on the input provided. LO changes can invalidate phase synchronization.
|
||||||
|
* - AGCs are set to manual mode at predetermined hardware gains for TX and RX. Gain changes can invalidate phase synchronization.
|
||||||
|
*
|
||||||
|
* Phase synchronization is valid until the LOs are retuned or sample rates change or gains are modified.
