ps4000aGetTimebase

PICO_STATUS ps4000aGetTimebase

(

int16_t handle,

uint32_t timebase,

int32_t noSamples,

int32_t * timeIntervalNanoseconds,

int32_t * maxSamples

uint32_t segmentIndex

)

This function discovers which timebases are available on the oscilloscope. You should

set up the channels using ps4000aSetChannel first.

Applicability

All modes

Arguments

handle, the handle of the required device.

timebase, a code between 0 and 2

–1 that specifies the sampling

interval (see Timebases).

noSamples, the number of samples required. This value is used to

calculate the most suitable time unit to use.

* timeIntervalNanoseconds, on exit, the time interval between

readings at the selected timebase. If a null pointer is passed, nothing

will be written here.

* maxSamples, on exit, the maximum number of samples

available. This number may vary depending on the number of

channels enabled, the timebase chosen and the oversample

selected. If this pointer is null, nothing will be written here.

segmentIndex, the number of the memory segment to use.

Returns

PICO_OK

PICO_INVALID_HANDLE

PICO_TOO_MANY_SAMPLES

PICO_INVALID_CHANNEL

PICO_INVALID_TIMEBASE

PICO_INVALID_PARAMETER
