hi,

    i am using fmcomms 4 along with zc706 and running it on no os driver .i want to use a design in tdd application where i send and transmit the signal over same channel in tdd mode in agc gain set. i am able to do this in normal application. i switch between tx and rx by using spi calls ENSM given in no os driver. now my problem is that for my application i need very fast switching between tx and rx. can anyone tell me how much time it takes to switch between tx and rx in tdd mode as tx->alert->rx and rx->alert->tx. also i went through some disscussions and found out about fast lock profile being used in tdd for fast switching . as i am relatively unaware of this can anyone pls expalin to me what exactly is fast lock profile and how it is used . how do i enable it in my no os code as i use the same tx and rx lo frequency and also can you tell me how much time it would take to switch between states,it will be quite helpful,thanks

 

regards

rahul
