This is a QT-based graphical sink that takes in byte streams or floating point streams and plots a time_raster (spectrogram) plot.
This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.
Input stream: This expects a bit stream (0, 1 in the LSB of a byte). It will display packed bytes but the display will have to be autoscaled.
 
This sink can plot messages that contain either uniform vectors of float 32 values (pmt::is_f32vector) or PDUs where the data is a uniform vector of float 32 values.

Revision as of 14:10, 9 September 2019

This is a QT-based graphical sink that takes in byte streams or floating point streams and plots a time_raster (spectrogram) plot.

Input stream: This expects a bit stream (0, 1 in the LSB of a byte). It will display packed bytes but the display will have to be autoscaled.

This sink can plot messages that contain either uniform vectors of float 32 values (pmt::is_f32vector) or PDUs where the data is a uniform vector of float 32 values.

Parameters

(R): Run-time adjustable

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
