[Discuss-gnuradio] Residual Frequency?

Hi All,

I am trying to send a GSM modulated signal using the USRP and the RFX900 board using the 'tune' function as in the provided usrp examples:

r = self.u.tune(self.subdev._which, self.subdev, target_freq)

The desired frequency is 925.6MHz, and I am getting a -381.47m residual_frequency as shown below.

What will be the best way to correct that, so I get the signal modulated to the desired frequency?

Thanks in advance to all for your help!


Using TX d'board A: Flex 900 Tx MIMO B
r.baseband_freq = 930M
r.dxc_freq      = -4.4M
r.residual_freq = -381.47m
r.inverted      = False
