handle: the handle of the required oscilloscope
mode:
PS2000_ETS_OFF (0) - disables ETS
PS2000_ETS_FAST (1) - enables ETS and provides ets_cycles
cycles of data, which may contain data from previously returned cycles
PS2000_ETS_SLOW (2) - enables ETS and provides fresh data every
ets_cycles cycles. PS2000_ETS_SLOW takes longer to provide each
data set, but the data sets are more stable and unique
ets_cycles: the number of cycles to store. The computer can then select
ets_interleave cycles to give the most uniform spread of samples.
ets_cycles should be between two and five times the value of
ets_interleave.
ets_interleave: the number of ETS interleaves to use. If the sample
time is 20 ns and the interleave 10, the approximate time per sample will be
2 ns.
The effective sample time in picoseconds, if ETS is enabled
0: if ETS is disabled or one of the parameters is out of range
