Data Acquisition Toolbox

StopTriggerChannel

Specify the analog input channel serving as a hardware stop trigger source

Description

StopTriggerChannel defines the channel number to be used for the HwAnalog setting of the StopTriggerType property. The channel must be a member of the analog input channel list.

To associate a particular channel with the stop trigger, assign the channel's hardware ID number to the property. If you specify a channel object, then an error is returned.

Characteristics

Vendor	Keithley
Usage	AI, Common
Access	Read/write
Data Type	Double
Read-only when running	Yes

Values

Any defined analog input channel. The default value is an empty vector.

Example

Create an analog input object for the Keithley KPCI-3108 board and add eight channels.

• ai = analoginput('keithley',1);
  addchannel(ai,0:7);
  

Stop the acquisition when a falling voltage level of 0.1 volt is detected on the hardware channel with ID 2.

• ai.StopTriggerType='HwAnalog';
  ai.StopTriggerChannel = 2;
  ai.StopTriggerCondition = 'Falling';
  ai.StopTriggerConditionValue = 0.1;
