Description
The acquisition mode.
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.
Configures the Noise Suppressed Accu-
mulation properties.
Specifies whether the Noise Suppressed
Accumulation is active. This attribute
affects card behavior only when the Acquis-
ition Mode attribute is set to Averager.
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.
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.
This function returns the accumulated wave-
form which the ADC card has acquired for
the specified channel. This waveform is from
a previously initiated accumulated acquis-
ition in Averager or Peak Detection mode.
Returned waveform data units are raw accu-
mulated ADC values which may be con-
verted to Volts by the formula: V =
ScaleFactor * data + ScaleOffset.
This function returns the averaged waveform
which the ADC card has acquired for the spe-
cified channel. This waveform is from a pre-
viously initiated accumulated acquisition in
Averager or Peak Detection mode. Returned
waveform data units are Volts.
