(

int16_t handle,

uint32_t * timeUpper,

uint32_t * timeLower,

PS4000A_TIME_UNITS * timeUnits,

uint32_t segmentIndex

)

This function gets the time, as two 4-byte values, at which the trigger occurred. Call it

after block-mode data has been captured or when data has been retrieved from a

previous block-mode capture.

Applicability

Block mode, rapid block mode

Arguments

trigger point occurred

* timeLower, on exit, the lower 32 bits of the time at which the

trigger point occurred

* timeUnits, on exit, the time units in which * timeUpper and *

timeLower are measured. The allowable values are:

PS4000A_FS

PS4000A_PS

PS4000A_NS

PS4000A_US

PS4000A_S

segmentIndex, the number of the memory segment for which the
