Hi All,
i still read in the gnuradio documentation, that we can prevent
freezing graphical elements by inserting the throttle element before,
but how can i locate which element is freezed ?
Is there any hlp in <grc> or python modules which can be used for
tuning/debugging ?
I inserted for every element a throttle, but this doesn't help me out.
Usually, you only need one throttle per flow graph (anywhere in the flow
graph) when there are no usrp or audio blocks present.
I am unsure about the peak hold.
Are the gui elements freezing as in: the buttons/controls do not
respond, or freezing as in the waveform has stopped updating on the screen?

Hi and thanks for your response,
i am using a usrp-source and a fft-sink and peakdetect+scope-sink.
only the screen with the wave form freezes, the buttons of the scope
and the fft sink are not freezing. This seems to appear mostly when
there are many peaks i think, but i can not attest this.
The only think i change before it freezes is the Signal frequency
of my signal generator, which sends data to the LF-RX db.
Regards Markus
