Re: Time to Switching Frequence

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' ?

It's not specified. It'll be variable and will most likely be more in the order of milliseconds than microseconds.

A much better plan would be to use the two channels of the UmTRX and tune one to Downlink and one to Uplink.

Cheers,
