[Discuss-gnuradio] does usrp.source_c do down conversion?

[pengyu zhang]

Hi,

A 250 kHz signal is modulated by a 900 MHz carrier wave and sent to a receiver. The receiver is configured with the following code. Does usrp.source_c do down conversion? I mean is the output of the receiver a 900 MHz signal or a 250 kHz signal? Thanks very much.

Receiver configuration code:

rx = usrp.source_c(0, dec_rate, fusb_block_size = 512, fusb_nblocks = 8)

r = usrp.tune(rx, 0, rx_subdev, freq)

Thanks,

Pengyu
