Spectrum Analyzer - Unknown Window Function Error

[vijaysukumarannair]

Issue: The spectrum plot window does not show any signal when spectrum analysers "start sweep" button is clicked.

Error: _The windowfunction of oscplot.c throws "unknown window function" as error.

Root Cause:
File: oscplot.c Function: _update_transformsettings Code: _For plot_type == SPECTRUM_PLOT, settings->fftwin is not updated.

Fix: File: oscplot.c Function: _update_transformsettings Add below line within the condition block "else if (plot_type == SPECTRUM_PLOT)" FREQ_SPECTRUM_SETTINGS(transform)->fft_win = gtk_combo_box_text_get_active_text(GTK_COMBO_BOX_TEXT(priv->fft_win_widget));
