Detailed Description

Though libuhd is designed to be re-entrant, there are some indications that all control functions (set_freq, gain, and other operations) should originate from a single thread.

USRPCtrl does that.

USRPCtrl listens on the Command Stream message channel for requests from other components (including the SoDa::UI listener) and dumps status and completion reports back onto the command stream channel.

Parameters

ant	the requested antenna
rxtx	select receiver or transmitter

Implements SoDa::RadioControl.

◆ setClockSource()

bool SoDa::USRPCtrl::setClockSource ( Command::ClockSource src )

virtual

Some radios support multiple choices for the main reference clock source.

As an example, the USRP N200 can lock its master clock to an external 10 MHz reference or to an internal TCXO.

This method chooses that reference source.

Parameters

src	if src is in the sources list, set the reference source to src

Returns: true if the source name is valid, false if otherwise or if there is only one choice.

Reimplemented from SoDa::RadioControl.

◆ setLOFreq()

double SoDa::USRPCtrl::setLOFreq	(	double	freq,
		SoDa::RXTX	rxtx )

virtual

Set the front-end (LO + DDS) frequency to 'freq' This includes setting the PLL front end synthesizer as well as the FPGA resident digital synthesizer.

Parameters

freq	target frequency (LO and DDS and RadioRX/TX NCO combined)
rxtx	select receiver or transmitter

Returns: The actual LO frequency.

The actual LO frequency may differ from the requested frequency by a small margin. Some radios may have a tuning step that is more than a few Hz. In this case we adjust the LO in the RX and TX objects. (This may be a bigger deal for the TX object as we like to do all the modulation there at baseband and assume the hardware takes care of the carrier frequency.

Typically, the call for a receive request would look like this:

actual_lo_freq = setLOFreq(144.215e6, SoDa::RX)

If the target LO can tune in 20 kHz intervals, the actual LO would be 144.100e6 and the if_freq would be 115e3 Hz. This would allow a "clean" window from 144.115 Mhz to 144.325 MHz in the spectrogram display. The LO would need to be changed if the next frequency was greater than 144.240 or less than 144.205 (I think)

On the transmit side, the offset may be dictated by the frequency stepping increment in the front-end LO.

To keep everything civilized, setLOFreq should never be called by any other agent than the RadioControl object. (Not even its sub-classes.)

Implements SoDa::RadioControl.

◆ setRFGain()

float SoDa::USRPCtrl::setRFGain	(	float	gain,
		SoDa::RXTX	rxtx )

virtual

set tain on the RX or TX side

Parameters

gain	gain - if not in range, we'll pick something good
rxtx	receive or transmit?

Returns: the actual gain setting

Implements SoDa::RadioControl.

◆ setSampleRate()

void SoDa::USRPCtrl::setSampleRate	(	float	rate,
		SoDa::RXTX	rxtx )

virtual

Set the RX or TX sample rate.

Parameters

rate	sample rate (in samples/sec)
rxtx	choose RX chain or TX chain

Implements SoDa::RadioControl.

◆ setTXEna()

void SoDa::USRPCtrl::setTXEna	(	bool	tx_on,
		bool	full_duplex )

inlineoverridevirtual

Enable or disable the transmit hardware chain, including the antenna relay and PA enable.

In half-duplex mode the RX chain should also be muted.
