Hello Marcus: Thank you for the quick reply. My initial thought was that the external code would query the grc block at a rate of 32kHz. I WAS assuming that there would be a unique value available every 1/32000s. Since this is not the case, I'm left wondering how best to get all 32000samples per second out of this block and into an array in python so that I can manipulate the data. It seems as though this may be a more in depth question than I realized.
-Ed ------------------------- Hi Ed, to what do you need that number "delivered"? That's the interesting point here; whether your external code "polls" a function, or expects to get a message of some sorts, or listens on a socket, or... Also note that it's not really like there's a constant "trickle" of random numbers, one every 1s/32000; GNU Radio is buffer-based, meaning that throttle gets a block of e.g. 4096 input items, passes them, and then waits 4096/32000 until it looks for new input.

I’m seeking a method to ‘expose’ the floating point number to external python code. This code would need to be updated at every 'tic' of the sample rate. Initially I had considered using the probe function but, from what I have read, it appears that is not appropriate for such a fast update rate. Any suggestions would be appreciated.
