Hi, I wanna know the frequency drift of WBX daughterboard.I think it may depend on the stability of WBX oscillator.How can I calculate it? Thank you.

Hi, The WBX frequency stability is determined by the accuracy of the USRP clock signal. For example, the USRP2 has a 100MHz internal clock which can be locked to a 10MHz external source such as GPSDO for better frequency stability. See the following url for more info: http://gnuradio.org/redmine/projects/gnuradio/wiki... GSM base stations have very accurate GPS disciplined clocks in them and 'Kalibrate' allows you to measure your device's frequency stability by using a mobile base station as a reference.
