[Discuss-gnuradio] Tx path questions

[Ronaldo Nunez]

Hello,

 

I have a doubt about coarse modulation in AD9862 (tx path).

I saw in the faq (http://gnuradio.org/trac/wiki/UsrpFAQ/ADC)  "...Block B only moves the signal +/- fs/4 or fs/8"...

OK, but when it moves fs/4 and when it moves fs/8? Is that controllable by software?

 

Another question:

Is the DAC frequency (fdac in the AD9862 datasheet) the same as target_freq parameter in the tune function?

 

Thank you

 

Regards
