UHD: get_center_freq?

GNU Radio
1

gr-usrp has set_tx_freq and tx_freq

uhd has set_center_freq but no get_center_freq or center_freq- I’m
trying to port some USRP1 python code to UHD and there doesn’t seem to
be a clear analog.

Have I overlooked something?

Thanks for any input/help!

The uhd has a get/set_rx/tx_freq. Did I forget to swig up the get_freq
for the source and sink wrappers?

Sorry for the delay- I sent this 02/02/11 from an email that’s not
subscribed.

I couldn’t find one…

This is what I could find anyway…

I’m usually missing something dumb when I put myself on the line and
post, but I’m happy to take my grains of salt and have a solution :slight_smile:
