Dwell Burst Measurement
'This program makes 34802 measurements of two single-ended channels at
'93750 Hz. Sample pattern is 1,1,1..., pause, 2,2,2..., pause.
'Measurement cycle is repeated every 2 Sec. The following programming features are
'key to making this application work:
'--PipelineMode.enabled.
'--Dash (-) placed before channel number.
'--Measurement count per channel set with VoltSE() Count= 34802 .
'--Measurement speed set with VoltSE() [SampleRate (Hz)]=93750 .
'--Scan() BufferOption increased to 5.
'NOTES:
'--Sampling occurs at the beginning of the Scan() interval.
'--All measurements for one channel are placed in a single large variable array.
'--The large array is stored in a single long record in the data table.
'--The exact sampling interval is calculated as follows:
' SampleTime = INT(MuxTime *( Reps + 1) + 2 ms). MuxTime=multiplexed measurement time.
