Analog Output Properties

Analog output base properties are divided into two main categories: common properties and channel properties. Common properties apply to every channel contained by the analog output object, while channel properties can be configured for individual channels.

Common Properties

The analog output common properties are grouped into the following categories based on usage.

Analog Output Basic Setup Properties
SampleRate	Specify the per-channel rate at which digital data is converted to analog data.
TriggerType	Specify the type of trigger to execute.

Analog Output Trigger Properties
InitialTrigger Time	Indicate the absolute time of the first trigger.
TriggerFcn	Specify the M-file callback function to execute when a trigger occurs.
TriggersExecuted	Indicate the number of triggers that execute.
TriggerType	Specify the type of trigger to execute.

Analog Output Status Properties
Running	Indicate whether the device object is running.
SamplesAvailable	Indicate the number of samples available per channel in the engine.
SamplesOutput	Indicate the number of samples output per channel from the engine.
Sending	Indicate whether data is being sent to the hardware device.

Analog Output Hardware Configuration Properties
ClockSource	Specify the clock used to govern the hardware conversion rate.
SampleRate	Specify the per-channel rate at which digital data is converted to analog data.

Analog Output Data Management Properties
MaxSamplesQueued	Indicate the maximum number of samples that can be queued in the engine.
RepeatOutput	Specify the number of additional times queued data is output.
Timeout	Specify an additional waiting time to queue data.

Analog Output Callback Properties
RuntimeErrorFcn	Specify the M-file callback function to execute when a run-time error occurs.
SamplesOutputFcn	Specify the M-file callback function to execute every time a predefined number of samples is output for each channel group member.
SamplesOutput FcnCount	Specify the number of samples to output for each channel group member before a samples output event is generated.
StartFcn	Specify the M-file callback function to execute just before the device object starts running.
StopFcn	Specify the M-file callback function to execute just after the device object stops running.
TimerFcn	Specify the M-file callback function to execute whenever a predefined period of time passes.
TimerPeriod	Specify the period of time between timer events.
TriggerFcn	Specify the M-file callback function to execute when a trigger occurs.

Analog Output General Purpose Properties
BufferingConfig	Specify the per-channel allocated memory.
BufferingMode	Specify how memory is allocated.
Channel	Contain hardware channels added to the device object.
EventLog	Store information for specific events.
Name	Specify a descriptive name for the device object.
OutOfDataMode	Specify how the value held by the analog output subsystem is determined.
Tag	Specify a device object label.
Type	Indicate the device object type.
UserData	Store data that you want to associate with a device object.

Channel Properties

The analog output channel properties are given below.

Analog Output Channel Properties
ChannelName	Specify a descriptive channel name.
DefaultChannel Value	Specify the value held by the analog output subsystem.
HwChannel	Specify the hardware channel ID.
Index	Indicate the MATLAB index of a hardware channel.
NativeOffset	Indicate the offset to use when converting between the native data format and doubles.
NativeScaling	Indicate the scaling to use when converting between the native data format and doubles.
OutputRange	Specify the range of the analog output hardware subsystem.
Parent	Indicate the parent (device object) of a channel.
Type	Indicate a channel.
Units	Specify the engineering units label.
UnitsRange	Specify the range of data as engineering units.
