Detailed Description

Base class for USRP blocks.

Note that many of the functions defined here differ between Rx and Tx configurations. As an example, set_center_freq() will set the Rx frequency for a usrp_source object, and the Tx frequency on a usrp_sink object.

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.

Exceptions

◆ set_power_reference()

virtual void gr::uhd::usrp_block::set_power_reference	(	double	power_dbm,

pure virtual

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().

Parameters

power_dbm	The power reference level in dBm
chan	the channel index 0 to N-1

Exceptions

std::runtime_error if the underlying UHD version does not support the power API.

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.

Parameters

stream_args New stream args.

Exceptions

std::runtime_error if new settings are invalid.
