Interface
Method / Property name
Description
IAqMD3TriggerSourceSelfTrigger
AbortGeneration
Stops the generation of the self-trigger signal
previously initiated.
InitiateGeneration
Starts the generation of the self-trigger sig-
nal.
Mode
Defines the self-trigger signal generation
mode.
PulseDuration
Defines the self-trigger signal pulse duration.
IAqMD3TriggerSourceSelfTrigger
SquareWave
Configure
Configures the square wave signal prop-
erties of the self-trigger generator. Calling
this function will automatically set the self-
trigger mode to Square Wave.
DutyCycle
Configures the duty cycle of the self trigger
square wave signal. Behavior depends on
the configuration of the Slope property (e.g.
if Slope is set to positive DutyCycle defines
the percentage that the square wave is in the
high state). Units are percentage of the
period.
Frequency
Specifies the frequency of the self-trigger
square wave signal. The units are Hertz.
Slope
Specifies whether a rising or a falling edge of
the generated waveform triggers the ADC
card.
IAqMD3TriggerSourceSelfTrigger
CustomWave
LoadConfigurationFile
Loads the configuration for the self-trigger
generator from a specified configuration file.
Calling this function will automatically set the
self-trigger mode to Custom Wave.
IAqMD3Acquisition
Mode
The acquisition mode.
IAqMD3Acquisition
NumberOfAverages
Specifies the number of waveforms to aver-
age in the record. This attribute affects card
behavior only when the Acquisition Mode
attribute is set to Averager or Peak-
Detection.
IAqMD3ChannelAccumulationNSA
Configure
Configures the Noise Suppressed Accu-
mulation properties.
Enabled
Specifies whether the Noise Suppressed
Accumulation is active. This attribute
affects card behavior only when the Acquis-
ition Mode attribute is set to Averager.
NoiseBase
Specifies the noise base value for the Noise
Suppressed Accumulation. The noise base
is subtracted from data values which are
higher than the configured threshold. The
units are ADC counts.
Threshold
Specifies the threshold of the Noise Sup-
pressed Accumulation. Each data value
must exceed the threshold value to be
entered into the sum. The units are ADC
counts.
