Query if this device is capable of absolute power levels
If true, the set_power_reference() and get_power_reference() APIs can be used as well. Note that if the underlying UHD version doesn't support power APIs, a warning will be printed, and the return value is always false.

Tune the selected channel to the desired center frequency.
This is a wrapper around set_center_freq() so that in this case, the user can pass a single frequency in the call instead of having to generate a tune_request_t object.

A timed command will back-pressure all subsequent timed commands, assuming that the subsequent commands occur within the time-window. If the time spec is late, the command will be activated upon arrival.

Set the normalized gain.
The normalized gain is always in [0, 1], regardless of the device. 0 corresponds to minimum gain (usually 0 dB, but make sure to read the device notes in the UHD manual) and 1 corresponds to maximum gain. This will work for any UHD device. Use get_gain() to see which dB value the normalized gain value corresponds to.
Note that it is not possible to specify a gain name for this function.

norm_gain | the gain in fractions of the gain range (must be 0 <= norm_gain <= 1) |

Set the absolute power reference level for this channel
Note that this API is available for certain devices only, and only if calibration data is available. Refer to the UHD manual for greater detail: https://files.ettus.com/manual/page_power.html
In a nutshell, using the power reference will configure the device such that a full-scale signal (0 dBFS) corresponds to a signal at the antenna connector of power_dbm
. After calling this function, the device will attempt to keep the power level constant after retuning, which means the gain level may be changed after a re-tune.
The device may coerce the available power level (for example, if the requested power level is not achievable by the device). The coerced value may be read by calling get_power_reference().
power_dbm | The power reference level in dBm |
chan | the channel index 0 to N-1 |

Update the stream args for this device.
This update will only take effect after a restart of the streaming, or before streaming and after construction. This will also delete the current streamer. Note you cannot change the I/O signature of this block using this function, or it will throw.
It is possible to leave the 'channels' fields of stream_args
unset. In this case, the previous channels field is used.
