Detailed Description

GUI for the inspector toolkit.

This GUI uses QT and QWT to create a graphical interface to control the inspector and get feedback about the detected and analyzed signals.

The PSD estimation of the Signal Detector block gets displayed here along with signal markers and informations. Manual signal selection can be done within the GUI created by this block.

Analysis blocks can pass information to the GUI block by providing messages in the tuple format

((pmt::intern("signal"), pmt::from_uint64(signal_no)), (pmt::intern("description1"), pmt::from_float(value1)), ...)

Controls: Use CTRL+LeftMouse to zoom, RightMouse to zoom out. This prevents confusion when in manual selection mode, where the signals are selected with LeftMouse.

Message ports:

map in: takes RF map from Signal Detector block and visualizes the included information in the plot
analysis_in: takes messages of analysis blocks and displays their content in the GUI plot.
map out: passes either the input message when manual selection is deactivated or passes RF map according to the user's manual settings.

Build a GUI sink instance.

Parameters

samp_rate	Sample rate of the input signal.
fft_len	Vector input size and number of PSD sample points
cfreq	Center frequency of source. Set to 0 if only relative frequencies are desired downstream.
rf_unit	Determine which unit the GUI uses to display frequencies
msgports	Number of message ports for analysis feedback
manual	Enable manual signal selection
parent	QWidget parent
