ps3000_set_trigger
short ps3000_set_trigger ( short handle,
This function is used to enable or disable triggering and its parameters. Triggering is not available in
streaming mode.

PS3000_ETS_OFF
ETS and provides ets_cycles of data, which may contain data from previously
returned cycles,

cycles.
ets_cycles
data set, but the data sets are more stable and unique.
ets_cycles, Specifies the number of cycles to store: the computer can then
select
ets_interleave
should be between two and five times the value of
ets_cycles
ets_interleave.
ets_interleave, Specifies the number of ETS interleaves to use. If the
sample time is 20ns and the interleave 10, the approximate time per sample will
be 2 ns.
If ETS is enabled, the effective sample time will be returned.
Zero if ETS is disabled or one of the parameters is out of range.

(1),
PS3000_CHANNEL_B
PS3000_EXTERNAL(4) or PS3000_NONE(5). Channels C and D are not
available on all models.
threshold, the threshold that the trigger event is to take place. This is scaled
in 16bit ADC counts at the currently selected range. If an external trigger is
enabled the range is fixed at +/-20V.
direction, use PS3000_RISING(0) or
delay, This specifies the delay, as a percentage of the requested number of
data points, between the trigger event and the start of the block. It should be in
the range -100% to +100%. Thus, 0% means that the first data value in the
block, and -50% means that the trigger event is in the middle of the block.
auto_trigger_ms, the delay in ms after which the oscilloscope will collect
samples if no trigger event occurs. If this is set to zero the oscilloscope will wait
for a trigger indefinitely.
if one of the parameters are out of range, otherwise 1.
