Moved Code block section for clock sync setup block from later stage to
earlier stage before check Ref and LO Lock detect block. Specifically
moved `//clock sync setup is complete do timed tuning of LOs and NCOs`
section.
This helped resolve the `Error: AssertionError: lo_locked.to_bool()`
Modified example to support demonstratig the X440 phase repeatability
performance. Change is compatible with all supported devices, but only
improves phase repeatability performance of X440.
Separated loops configuring radio properties and converted setting carrier
frequency into timed commands. This required moving this code to a later
part in the programming flow, after all the clock source settings are
applied and the LO locks are confirmed.
- tx_waveforms fixes:
- Fixed power bug. Changed loop style to 'for each' in order to avoid this
issue in the future
- tx_samples_from_file:
- Fixed bug where channels 1 and higher could not be configured correctly.
- Added the 'power' argument.
- Added support for multiple channels.
- Re-added 'channel' argument for backwards compatibility.
- Added additional error checking.
- Changed help descriptions to match other example apps.
This changes the behaviour of the examples in a way that leaving
out the --ref argument will not force it to be 'internal'. Previously,
the following command:
rx_samples_to_file --args type=xxx,clock_source=external
would still use the internal reference, because the default value for
--ref was internal, and no other value for --ref was provided. Even
worse, the following command:
rx_samples_to_file --args \
type=xxx,clock_source=external,time_source=external
might throw errors/warnings, because internal clock source plus external
time source is generally not supported, and the example would force the
clock source to be internal unless `--ref internal` was also provided.
For all cases that `clock_source` or `time_source` were not given as
a device argument, this is a no-op because `internal` is the default
value anyway.
In two examples, this includes minor code changes:
- In rfnoc_radio_loopback, if both --ref and --pps were given, we now
use set_sync_source() to speed up setting the reference sources. On
the N310/N300 series in particular, this saves a few seconds at
initialization over the previous implementation (which set clock and
time reference separately).
- In test_dboard_coercion, the code would fail without a default value
for --ref, so we no longer require such a default value.
Its behaviour is almost identical to std::lround, which we use instead.
The only downside of std::lround is that it always returns a long, which
we don't always need. We thus add some casts for those cases to make the
compiler happy.
If you run
tx_waveforms --power -20 [other args]
it will try to set the out power to -20 dBm. The signal amplitude is
factored in, so changing --ampl will not change the actual TX power
unless it causes clipping, or becomes too low.
If the USRP does not support setting a power, the program will terminate
early. If it does support setting a power, but can't reach the requested
power, it will coerce, and print the actual, available power.
Remove UHD call to elevate thread priority to realtime. Setting all
threads to the same realtime priority can cause the threads to not share
access to the network interface fairly, which adversely affects
operation of the worker threads in UHD.
Turning off clang formatting around the program option declarations.
clang-format makes them looks bad an unreadable because it thinks the
options are function calls or something.
Move filling the TX buffer outside the critical path. Now, we pre-fill
the TX buffer before entering the send loop (and before setting the
TX stream time), and fill the TX buffer after calling send() (for the
next iteration).
* Added support for new CBX-120, SBX-120, and WBX-120 daughterboards
* Added implementation of Integer-N tuning for all CBX, SBX, and WBX daughterboards
* Added --int-n option to examples to show how to use Integer-N tuning API
* Removed duplicate ADF4350/ADF4351 code and moved it to common/adf435x_common.cpp
