[Discuss-gnuradio] fine offset for XCVR2450

[Apurv Bhartia]

Hi Everyone, 

Does the XCVR2450 (when acting as a transceiver) exhibit the same 
frequency offset for both its RX and TX operations in OFDM? I know fine offset 
value can change depending on various factors, and to alleviate that 
problem, I'm using an external clock (without the GPS) connected to my 
N200. 

When I use the XCVR only as a receiver, I can see that the fine offset 
now is much more stable (as compared to when the external clock isn't 
used) for several packets. However, when it acts as a transceiver, it 
seems to me that the fine offset can fluctuate quite a bit between the 
RX and the TX ends. 

I don't know if it helps but I've also tuned the UHD using 
(http://files.ettus.com/uhd_docs/manual/html/general.html#tuning-notes).
 I've used the same setting for both the rx_freq and tx_freq. 

Thanks,
Apurv
