I have created a few example applications in gr-qtgui/src/python. There are two that are similar to usrp_fft.py and usrp2_fft.py where you can tab through the different views such as the PSD, waterfall, and oscope.
The other one is a application to allow you to examine the digital modulators. Using the constellation view tab, you can see what happens to the signal through the carrier recovery and timing loop. You can then play with the noise, timing, and frequency offset of the channel model as well as some of the gain values of the receiver. If you are working with the digital modulators, this can help you understand what values to use and how they affect the system.
