' AQUIRE_TYPE - Sets the acquisition mode, which can be NORMAL,
' PEAK, or AVERAGE.
myScope.WriteString ":ACQUIRE:TYPE NORMAL"
' AQUIRE_COMPLETE - Specifies the minimum completion criteria for
' an acquisition. The parameter determines the percentage of time
' buckets needed to be "full" before an acquisition is considered
' to be complete.
myScope.WriteString ":ACQUIRE:COMPLETE 100"
' DIGITIZE - Used to acquire the waveform data for transfer over
' the interface. Sending this command causes an acquisition to
' take place with the resulting data being placed in the buffer.
Programming Examples
' Start data acquisition.
' Stop the data acquisition.
' Turn channel 1 off.
' Turn channel 1 on.
