DDSChan

class qtrfblocks.DDSChan(app: QWidget, controller: AD9913Controller)

Create an instance of DDSChan.

Parameters:

• app (QWidget) – The parent application for the channel display.

• controller (rfblocks.AD9913Controller) – AD9913 DDS controller

LVL_UNITS

alias of Lvl_Units

build_ui() → QGroupBox

Build on-screen UI components for a DDS_2 channel.

property chan_id: str

The channel identifier.

configure()

Update the DDS hardware using the currently set configuration.

property ctl: AD9913Controller

Return a reference to the AD9913Controller.

property dbm: float

Return the DDS output level (in dBm).

dump_config() → Dict

Return the current configuration for this clock module.

Returns:

A dictionary containing the current clock modules configuration:

freq:

The currently set output frequency (in MHz).

channels:

A dictionary containing the channel configurations keyed using the channel id.

property enabled: bool

property level: float

Return the DDS output level (in DDS DAC units).

load_config(config: Dict) → None

Set the current configuration for this clock module.

Parameters:

config (Dict) – A dictionary containing the module configuration to be set.

property millivolts: float

Return the DDS output level (in millivolts RMS)

property phase: float

Note that configure() must be invoked in order to update the DDS hardware

set_freq(f: float) → None

Set the DDS output frequency (in MHz).

Note that configure() must be invoked in order to update the DDS hardware

set_level(l: float) → None

Set the DDS output level (in DDS DAC units).

Note that configure() must be invoked in order to update the DDS hardware

set_millivolts(mv: float)

Set the DDS output level (in millivolts).

Note that configure() must be invoked in order to update the DDS hardware

set_phase(p: float) → None

Set the DDS phase offset (in degrees).

Note that configure() must be invoked in order to update the DDS hardware

set_pmod(state: bool) → None

Note that configure() must be invoked in order to update the DDS hardware

set_state(flag: int)

Set the DDS channel state.

Parameters:

flag (int) – This should be either ad9913.POWER_UP or ad9913.POWER_DOWN.

property state: int

The state of the DDS channel. Either powered up or powered down.

update_chan_freq(f: float) → None
