Hello list,
after a lot of working, I finally came around to write a minimal example
to show what does not work.
To make it short: from python, calling
src = uhd.usrp_source(...)
[...]
src.set_command_time(uhd.time_spec(<a second in the future>))
src.set_center_freq(1e9)
src.clear_command_time()
does _not_ issue the tuning request a second in the future; it is
executed right away.
However, the next get_time_now() call happens a second delayed.
The complete test can be found under
https://gist.github.com/marcusmueller/6251825 or cloned via
git clone https://gist.github.com/6251825.git
Could please someone verify this problem is specific to my system?
Thanks in advance,
Marcus
