Error executing usrp2_wfm_rcv.py

Hello.

Can this variable “step_size” have an arbitrary value? I tried several
times
and I always get this message:

(python:3293): Gtk-CRITICAL **: IA__gtk_range_set_range: assertion `min
<
max’ failed

and nothing at the USRP2 output (around -400 dB)

By the way, I am using BasicRX.

Thanks!

Eduardo.

OK, found the problem. The problem is that for a BASIC_RX, the
available settable gain range is [0,0], since it has no settable gain
elements.
Which means the slider won’t work properly. Perhaps one could put
in a conditional prior to creation of the slider that checks for [0,0].
And doesn’t create the slider at all if there is no usable gain
range.

The step size can be small, but in this case, the GTK package is
complaining that the “MIN” and “MAX” values on the slider are reversed,
or don’t conform to the required “MIN < MAX” requirement.
