Arbitrary Waveform Generator (AWG)

Arbitrary waveform generators.

Instrument and Abstract Driver

InstroAWG	AWG instrument.
AWGDriverBase	Vendor AWG driver contract.

Vendor Drivers

Vendor	Model	Description
Keysight	33521B	SCPI driver for the Keysight 33521B arbitrary waveform generator.
Rigol	DG1022Z	SCPI driver for the Rigol DG1022Z two-channel arbitrary waveform generator.

Types & Configuration

Sine	Sine waveform definition.
Square	Continuous rectangular wave; high for duty_cycle_pct percent of each period.
Sawtooth	Sawtooth waveform definition.
Triangle	Triangle waveform definition.
Pulse	Continuous rectangular wave (not single-shot); each period goes high for width_s seconds after delay_s.
Arbitrary	Arbitrary waveform definition; samples are normalized to [-1, 1] and scaled by amplitude/offset.
StaticValue	Static valued waveform definition.
AmplitudeMeasurementUnit
ModulationType
BurstType
BurstTriggerSource
GatePolarity
SweepType
SweepTriggerSource
convert_amplitude	Convert an amplitude value between measurement units for a waveform shape.

Configuration

AWGConfig	Validated config for constructing an InstroAWG from JSON.
ChannelConfig	Initial per-channel state applied on open(); the channel stays silent until its output is explicitly enabled.
VisaDriverConfig	Driver config for a VISA-connected AWG.
SineConfig	Sine waveform config.
SquareConfig	Square waveform config.
SawtoothConfig	Sawtooth waveform config.
TriangleConfig	Triangle waveform config.
PulseConfig	Pulse waveform config.
ArbitraryConfig	Arbitrary waveform config; samples are either given inline or read from a CSV file path.
StaticValueConfig	Static (DC) value config.
AmplitudeConfig	Output amplitude config; maps to InstroAWG.set_amplitude.
ModulationConfig	Carrier modulation config; maps to InstroAWG.set_modulation/modulation_enable.
ModulationTypeConfig	Modulation type and its magnitude; magnitude's meaning varies by name (see InstroAWG.set_modulation).
BurstConfig	Burst config; maps to InstroAWG's set_burst*/burst_enable setters.
SweepConfig	Sweep config; maps to InstroAWG's set_sweep*/sweep_enable setters.
build_waveform	Construct the runtime Waveform definition described by a waveform config block.
resolve_awg_from_config	Resolve a validated AWGConfig into the (name, driver, num_channels, config_publishers, poll_interval) InstroAWG needs.

Shared configuration

Class	Description
DeviceInfo	Device metadata.
TimingConfig	Timing configuration for instrument background polling.
NominalCorePublisherConfig	Publisher config for streaming to a Nominal Core dataset.
FilePublisherConfig	Publisher config for writing measurements to a local file.
