Re: The shortest pulse length

Thanks for the reply.

I mentioned in my response to David’s message that I’m purposefully
setting the duc frequency to 0 to transmit at baseband. Is using .tune
to do this better than the set_freq method even if I don’t want duc to
do anything to the signal?

Regards

Lance

Lance, you really want to be using tune, not set_tx_freq.
tune knows about all the daughterboards and does the right thing to
split the work between the digital upconverter and the RF front end (if
any).

Take a look at fm_tx4.py or fm_tx_2_daughterboards.py

The good thing about “tune” is that it works the same way with all
daughterboards. If you’re using Basic Tx or LF Tx boards, the end
result will be the same. “tune” will do all the work using the DUC.
