FMCOMMS1 Tx anamoly

Hello,

 

I would like to transmit a GMSK signal that is 1 Mbps. Everything looks good on the simulink spectrum wise. The output looks close to 1 MHz.

But when I transmit it via the FMCOMMS1 I see the bandwidth way more that I should see. It is in the order of 20 MHz. I am looking at the output of TX..

I am enclosing the simulink model and the I Q file I am loading.

 

Any ideas what I am missing here?

 

As usual, thanks for your help.
