- On the DFT visualization on sdr2-md1, you should see a peak representing the transmitted signal:
+ As we can see from the arguments passed to the application, we are transmitting a 1MHz sine wave as a signal using 2.4GHz as the carrier frequency. On the DFT visualization on sdr2-md1, you should see a peak representing the transmitted signal:

+
+ We can generate a different type of signal by changing the {{{wave-type}}} argument. For instance, if we transmit a square wave:
+ {{{#!shell
+ /usr/lib/uhd/examples/tx_waveforms --args="resource=rio0,type=x300" --wave-freq 1e6 --wave-type SQUARE --freq 2400e6 --rate 5e6 --gain 10 --ampl 0.2
+ }}}
+
+ We can see that the spectrum of the received signal now contains multiple peaks. This is the result of the spectral characteristics of a square wave.
