Hi All,

 

I have a project to monitoring ( air sniffer ) the data between GSM BTS and MS using UmTRX.

Uplink Transmission is delayed 3 slots than downlink from specification.

So when I sync. with BTS and get the downlink slot data, I must switch the freqs of receiver from downlink to uplink in less than 2 slots.

When the program call 'usrp_dev->set_rx_freq(wFreq)', How much time does the UmTRX switch to the 'wFreq' ?

 

Thanks in advance.
