Hi all,
If I open a new flow graph in GRC and select a QT GUI Bercurve Sink
block, the default parameters create 16 ports (connections) on the
block. The default in the "Num Curves" field is 1 and the default in the
"esno" field is numpy.arange(0.0, 4.0, .5), which is 8 values. I'm not
sure why there are 16 ports.
If you then change "Num Curves" to 2, the number of ports on the block
changes to 32. Also, if you change the value of "esno" to a different
range of values, it changes the number of ports. Is that on purpose?
Should the specified number of esno values be related to the number of
ports?
I would expect that the number of ports on this block is simply equal to
the number of curves specified. i.e., 2 in the "num curves" field
generates 2 ports on the block.
In fact, that is the behavior of the ber_curve_gen.grc example. However
if you start from a new flowgraph, there's a different behavior.
Any clarification on this would be appreciated. I'm working with GNU
Radio v. 3.7.9.1.
Thanks,
tracie
