On a fully fledged GR installation, there are two subcategories QT and WX, though your windows installation might lack one. You can use the QT FFT sink instead of the WX one, and use the QT entry box instead of the wx text box, if that is not available.

What you've posted is a screenshot of putty, an SSH client and terminal emulator for Windows, where you've logged in to a remote computer circe (most probably a linux system) and try to start gterm (a terminal emulator itself) there. That being a graphical program and you being only connected by a text terminal makes the program unable to launch. However, this has nothing to do with GNU Radio. You need a working GNU Radio installation on a computer you have graphical access to in order to use the GRC (GNU Radio Companion), which is a graphical user interface. Since you do mention a version number, I guess you _have_ installed GNU Radio somewhere, most probably your own Windows PC. In that case, you will find GNU Radio there. If there is a GNU Radio installation on circe.jpl.nasa.gov, you can't use the graphical user interface.

Re: [Discuss-gnuradio] Sine wave of only 3 cycles
On Thu, Jan 30, 2014 at 10:22 PM, Activecat active...@gmail.com wrote: Dear Sirs, But, another problem arisen. There is a WX GUI Scope Sink in the middle of the flow-graph to plot the instantaneous reading. When the data stream stop by the Head Block, says, at time=t1, the WX GUI Scope Sink starts to show zero reading. The question is, how to see the plot between time=0 and time=t1 ? The workaround is to save the data into a file, then plot it using external tool. This is off-line approach. Is there any online approach that doesn't require any external plotting tool, to view the GUI plot between time=0 and time=t1, after the Head Block terminates the data stream? Regards, activecat You can try to use the QTGUI tools instead of the WX ones. When the data stops, the QTGUI sinks should not update, so it will show you the last plotted samples. But be aware that it's a sampling approach to plotting. Basically, it waits for enough samples to plot one full graph (1024 by default), so it needs to see this amount before it'll update. However, since you're stopping the flowgraph, don't be afraid of the off-line approach. That might be the best way to go. The on-line approach is designed for streaming data, so what you're asking to do is a bit of a different situation that we'd normally work with. Also, note that we ship a handful of off-line plotting tools with GNU Radio. There's a set called gr_plot_* that use scipy and Matplotlib to plot the graphs. I made some newer ones called gr_*_plot_* that uses QT. There not full-featured and may be a bit buggy, but the idea with these is to have a common feel and UI between using the QTGUI sinks inside a flowgraph and these off-line plotting tools.

If you want to have a three period sine signal, the python is short #import numpy as np f_sin = 1.0 f_sample = 16.0 periods = 3.0 s_per_period = f_sample/f_sin sinevalues = np.sin(np.linspace(0, periods*2*np.pi, periods*s_per_period) ) sinevalues.astype(np.float32).tofile(filename) this will be the same data format as written by the file sink.

Saying you want to get to know GNU Radio implies you're interested in coding or assembling flowgraphs to possibly make an application. Are you looking for an issue with the GNU Radio codebase to get in to contributing, or making applications?
