I have looked at that file and you have made gain, frequency, and LO offset
variables and then you send messages every 2 secs. When I run the file, I
try to change the frequency from 2.4 to 2.5 G using the glider in the GUI.
It should change the value of the variable which should be reflected in
Hello,
For every message which you send UHD would change the gain once. So in
order to alternate every 100ms you would send 10 messages a second,
advancing the timestamp value by 100ms each time. The example I linked to
shows the frequency and gain being changed every two seconds. You'll just
Also I want to keep doing this in a loop (the values keep alternating after
an interval). Will it be possible through the command port interface ?

Hi Derek,
Thank you for your email. If you could find that file it would be really
helpful. What I want to do is to alternate between two or more values of
gain after specific intervals. Can I alternate like this using the command
port interface? How will the block USRP sink block know which
Hello,
The command port interface can be used to change the gain value. There is
an example of creating messages for tuning included in gr-uhd.

I've used a function probe to generate coarsely timed "tick"
Hi,
I want to alternate the gain of the USRP between two values after a certain
period of time. For example after 100 ms it should go from A to B and after
another 100 ms the value should go from B to A and so on.
Is there an easy way of doing this in the GNU Radio companion or would I
need to
