Analog Voltage Measurement: Cluster Burst
'This program makes 500 measurements of two single-ended channels at 500 Hz.
'Sample pattern is 1,2,1,2. Measurement cycle is repeated every 1 Sec. The following
'programming features are key to making this application work:
'--PipelingMode enabled.
'--Measurement speed set as follows:
' Scan() Interval=1, Units=Sec.
' SubScan() SubInterval=2, Units=mSec, and Count= 500.
'--Scan() BufferOption increased to 5.
'--At this measurement speed, CR800 processing is not fast enough to keep up with the
' sample rate. The result is a periodic skipped scan, which allows processing
' to catch up. To program for measurements without skipped scans, modify the
' measurement speed. For example.set Scan() Interval=3, Units=Sec, SubScan()
' SubInterval=3, Units=mSec, and Count=666.
