Detailed Description

Functions to control the clock output type.

Oscilloscopes can support supplying a clock output signal, use tiepie_hw_oscilloscope_get_clock_outputs() to determine the available clock outputs for an oscilloscope.

When an oscilloscope supports selecting a clock output signal, refer to the instrument manual for the location of the clock output and the specifications of the clock output signal.

Depending on the instrument, a clock output can support multiple output frequencies. Use tiepie_hw_oscilloscope_get_clock_source_frequencies() to determine which frequencies are supported.

By default the clock output is disabled (TIEPIE_HW_CO_DISABLED).

uint32_t length = tiepie_hw_oscilloscope_get_clock_output_frequencies(h_device, NULL, 0);
double* Frequencies = malloc(sizeof(double) * Length);
Length = tiepie_hw_oscilloscope_get_clock_output_frequencies(h_device, Frequencies, Length);
for(i = 0 ; i < Length ; i++)
{
printf("%f\n", Frequencies[ i ]);
}
free(p_frequencies);
