[[File:]] -	no_of_samples
number of samples required
[[File:]] -	time_interval
time interval between readings at the selected timebase. Use NULL if not required.
- INT	time_units

- INT	enabled
whether or not to enable the channel. The values are: 0=Disable / 1=Enable
- INT	dc
the impedance and coupling type. Values: 0=AC / 1=DC
