This enables querying the converter rate through the sensor API:
```python
>>> U = uhd.usrp.MultiUSRP("type=x4xx")
>>> print(U.get_tx_sensor('rfdc_rate').to_real())
3000000000.0

# The FBX has a field in its EEPROM which stores a rev_compat value. This
|
|
# tells us which other revisions of the FBX this revision is compatible with.
|
|
#
|
|
# In theory, we could make the revision compatibility check a simple "less
|
|
# or equal than comparison", i.e., we can support a certain revision and all
|
|
# previous revisions. However, we deliberately don't support Revision A (0x1),
|
|
# and we prefer to explicitly list the valid compat revision numbers we
|
|
# know exist. No matter how, we need to change this line everytime we add a
|
|
# new revision that is incompatible with the previous.
|
|
#
|
|
# In the EEPROM, we only change this number for hardware revisions that are
|
|
# not compatible with this software version.
