Which sample rate is set by uhd.single_usrp_source.set_samp_rate?

Dear all,

In my project, I am using uhd.single_usrp_source to set the
configuration for USRP N200 with LFRX DB. The sub-function set_samp_rate
is used to set the sample rate, though I am not sure this sample rate
setting is set to which signal, before Digital Down Conversion or after?
Originally, I guess this set_samp_rate function takes the place of
set_decim and set_interp in USRP1 Mboard, though it turned out that the
sample rate set by set_samp_rate function need to be at least doubled
the RF frequency, otherwise, the received signal cannot be completely
recovered. I am curious the sample rate this function set is for which
signal? Thank you for your help in advance!

Dear a

I’m just going to go out on a limb here… It’s a sample source, so
setting the RX sample rate.
