Member Function Documentation

◆ get_amplitude()

virtual double uhd::rfnoc::siggen_block_control::get_amplitude ( const size_t  port) const
pure virtual

Get the amplitude value for noise and sine wave data

Returns the current maximum amplitude of the data generated by the given port on the block. The value only applies to the noise and sine wave functions. Calling this function when in constant mode will return 1.0.

Parameters
portThe port on the block whose amplitude value to return
Returns
Amplitude value

◆ get_constant()

virtual std::complex< double > uhd::rfnoc::siggen_block_control::get_constant ( const size_t  port) const
pure virtual

Get the constant value to generate in constant mode

Returns the current constant value to be generated by the function generator on the given block when the block is configured in constant mode.

Parameters
portThe port on the block whose constant value to return
Returns
Constant value to generate

◆ get_enable()

virtual bool uhd::rfnoc::siggen_block_control::get_enable ( const size_t  port) const
pure virtual

Get the function generator stream enable flag

Returns the current enable flag for function generator stream data from the given port on the block.

Parameters
portThe port on the block to get the flag from
Returns
Function generator stream data enable/disable flag

◆ get_samples_per_packet()

virtual size_t uhd::rfnoc::siggen_block_control::get_samples_per_packet ( const size_t  port) const
pure virtual

Get the number of samples per packet to generate

Returns the current number of samples per packet generated by the function generator on the given block.

Parameters
portThe port on the block whose samples per packet value to get
Returns
Number of samples per packet to generate

◆ get_sine_phase_increment()

virtual double uhd::rfnoc::siggen_block_control::get_sine_phase_increment ( const size_t  port) const
pure virtual

Get the phase increment between samples in sine wave mode

Returns the current phase increment between successive samples generated by the function generator on the given block when the block is configured in sine wave mode.

Parameters
portThe port on the block whose phase increment to return
Returns
Phase increment between samples

◆ get_waveform()

virtual siggen_waveform uhd::rfnoc::siggen_block_control::get_waveform ( const size_t  port) const
pure virtual

Get the function generator waveform type

Returns the current waveform type for the given port on the block.

Parameters
portThe port on the block whose waveform type to return
Returns
Waveform type

◆ RFNOC_DECLARE_BLOCK()

uhd::rfnoc::siggen_block_control::RFNOC_DECLARE_BLOCK ( siggen_block_control  )

◆ set_amplitude()

virtual void uhd::rfnoc::siggen_block_control::set_amplitude ( const double  amplitude,
const size_t  port 
)
pure virtual

Set the amplitude value for noise and sine wave data

Sets the maximum amplitude of the data generated by the given port on the block. The hardware can generate function data with an amplitude between -1.0 and (2^15-1)/(2^15), or approximately 0.99997, so the provided value must reside within this range. However, for convenience, clients may pass 1.0 to get the maximum amplitude that can be generated.

Setting the amplitude applies only to the noise and to the sine wave functions. The value generated when in constant mode is the value that is configured via the set_constant() function. Calling this function when in constant mode will range check the amplitude value, but will otherwise have no impact on the generated signal.

Parameters
amplitudeAmplitude of sine wave and noise data
portThe port on the block whose amplitude value to set

◆ set_constant()

virtual void uhd::rfnoc::siggen_block_control::set_constant ( const std::complex< double >  constant,
const size_t  port 
)
pure virtual

Set the constant value to generate in constant mode

Sets the value that should be generated by the function generator on the given block when the block is configured in constant mode. The hardware can output a complex value where the real and imaginary components can be between -1.0 and (2^15-1)/(2^15), or approximately 0.99997, so the provided value must reside within this range. However, for convenience, clients may pass 1.0 for either component to get the maximum positive value that can be generated.

Parameters
constantThe constant value to generate
portThe port on the block whose constant value to set

◆ set_enable()

virtual void uhd::rfnoc::siggen_block_control::set_enable ( const bool  enable,
const size_t  port

pure virtual

Set the function generator stream enable flag

Enables or disables the stream of function generator data from the given port on the block.

Parameters
enableStream enable/disable flag
portThe port on the block to enable or disable

Set the number of samples per packet to generate

Sets the number of samples per packet to be generated by the function generator on the given block. The value will be coerced such that outgoing packets will not exceed the graph MTU.

Parameters
