InitialTriggerTime - Absolute time of first trigger

Description

For all trigger types, InitialTriggerTime records the time when Logging or Sending is set to On. The absolute time is recorded as a clock vector.

You can return the InitialTriggerTime value with the getdata function, or with the Data.AbsTime field of the EventLog property.

Characteristics

Values

The value is automatically updated when the trigger executes. The default value is a vector of zeros.

Examples

Create the analog input object ai for a sound card and add two hardware channels to it.

ai = analoginput('winsound');
chans = addchannel(ai,1:2);

After starting ai, the trigger immediately executes and the trigger time is recorded.

start(ai)
abstime = ai.InitialTriggerTime
abstime =
1.0e+003 *
    1.9990    0.0020    0.0190    0.0130    0.0260    0.0208

To convert the clock vector to a more convenient form:

t = fix(abstime);
sprintf('%d:%d:%d', t(4),t(5),t(6))
ans =
13:26:20
