OutOfDataMode - Specify how value held by analog output subsystem is determined

Description

When queued data is output to the analog output (AO) subsystem, the hardware typically holds a value. For National Instruments and Measurement Computing devices, the value held is determined by OutOfDataMode.

OutOfDataMode can be Hold or DefaultValue. If OutOfDataMode is Hold, then the last value output is held by the AO subsystem. If OutOfDataMode is DefaultValue, then the value specified by the DefaultChannelValue property is held by the AO subsystem.

Characteristics

Vendor	Measurement Computing, National Instruments
Usage	AO, common to all channels
Access	Read/write
Data type	String
Read-only when running	Yes

Values

{Hold}	Hold the last output value.
DefaultValue	Hold the value specified by DefaultChannelValue.

Examples

Create the analog output object ao and add two channels to it.

ao = analogoutput('nidaq','Dev1');
addchannel(ao,0:1);

You can configure ao so that when queued data is finished being output, a value of 1 volt is held for both channels.

ao.OutOfDataMode = 'DefaultValue';
ao.Channel.DefaultChannelValue = 1.0;
