gnuradio.qtgui

This is the gr-qtgui package. This package includes QT-based graphical sinks.

gnuradio.qtgui.sink_c(int fftsize, int wintype, double fc = 0, double bw = 1.0, string name = "Display", bool plotfreq = True, bool plotwaterfall = True, bool plottime = True, bool plotconst = True, QWidget parent = None) → qtgui_sink_c_sptr

A graphical sink to display freq, spec, time, and const plots.

This is a QT-based graphical sink the takes a complex stream and plots it. The default action is to plot the signal as a PSD (FFT), spectrogram (waterfall), time domain I&Q, and constellation (I vs. Q) plots. The plots may be turned off by setting the appropriate boolean value in the constructor to False.

gnuradio.qtgui.time_sink_c(int size, double bw, string name, int nconnections = 1, QWidget parent = None) → qtgui_time_sink_c_sptr

A graphical sink to display multiple signals in time.

This is a QT-based graphical sink the takes set of a complex streams and plots them in the time domain. For each signal, both the signal’s I and Q parts are plotted, and they are all plotted with a different color, and the and functions can be used to change the lable and color for a given input number.
