ps4000SetEtsTimeBuffers

PICO_STATUS ps4000SetEtsTimeBuffers

(

short handle,

unsigned long * timeUpper,

unsigned long * timeLower,

long bufferLth

)

This function tells the PicoScope 4000 driver where to find your application's ETS time

buffers. These buffers contain the timing information for each ETS sample after you

run a block-mode ETS capture. There are two buffers containing the upper and lower

32-bit parts of the timing information, to allow programming languages that do not

support 64-bit data to retrieve the timings correctly.

Note: ETS mode is not supported by the PicoScope 4262 oscilloscope.

Applicability

ETS mode only.

If your programming language supports 64-bit data, then you can

use ps4000SetEtsTimeBuffer instead.

Arguments

handle, the handle of the required device

timeUpper, a pointer to a set of 4-byte words, the time in

nanoseconds at which the first data point occurred, top 32 bits only

timeLower, a pointer to a set of 4-byte words, the time in

nanoseconds at which the first data point occurred, bottom 32 bits

only

bufferLth, the size of the timeUpper and timeLower arrays

Returns

PICO_OK

PICO_INVALID_HANDLE

PICO_NULL_PARAMETER
