pl1000SetInterval

PICO_STATUS pl1000SetInterval(

short handle,

unsigned long * us_for_block,

unsigned long ideal_no_of_samples,

short * channels,

short no_of_channels

)

This function sets the sampling rate of the unit.

The fastest possible sampling interval is 1 microsecond, when the number of samples

is 8129 divided by the number of channels active and the capture mode is

BM_SINGLE. Under all other conditions, the fastest possible sampling interval is 10

microseconds.

Arguments:

handle: handle returned from pl1000OpenUnit or

pl1000OpenUnitProgress

us_for_block: target total time in which to collect

ideal_no_of_samples, in microseconds

ideal_no_of_samples: the number of samples that you want to

collect. This number is used only for timing calculations.

channels: an array of numbers identifying the channels from which

you wish to capture data, from PL1000_CHANNEL_1 to

PL1000_CHANNEL_12 (for the PicoLog 1012) or

PL1000_CHANNEL_16 (for the PicoLog 1216).

no_of_channels: the number of channels in the channels array

Returns:

PICO_OK

PICO_INVALID_HANDLE

PICO_INVALID_CHANNEL

PICO_INVALID_TIMEBASE

PICO_NOT_RESPONDING

PICO_CONFIG_FAIL

PICO_INVALID_PARAMETER

PICO_NOT_RESPONDING
