Chapter 2 Utility Analog Input VIs
ADAC LabVIEW VI 34
ADAC AI Wave Scan
The ADAC AI Waveform Scan VI collects the specified number of samples at the
specified sample rate and returns the waveform data in a two dimensional array. This VI
typically acquires voltage readings on multiple channels, but may be used to collect
single channel points into its two dimensional array.
If the error in cluster contains an error from a previous VI call, this VI does nothing and
returns the error in cluster unmodified in the error out.
Board ID (0) Specifies the ADAC-LVi board ID number to be used in this acquisition.
The ID numbers are defined in the configuration file ADAC-LVi.con located in the
Windows main directory.
Channel List (0 (1)) Channel List is a string that specifies the analog input channel
numbers to acquire data from. Channel List is typically set to acquire multiple channels,
but may be used to collect single channels into its two dimensional array.
For boards that support input gain the channel list also specifies a separate gain value for
each channel. Gains are specified in parentheses after the channel number. For example,
"0(1),1(8),2(4)" is interpreted as channel 0 at a gain of 1, channel 1 at a gain of 8 and
channel 2 at a gain of 4.
