Detailed Description

Functions to control the oscilloscope resolution.

The resolution determines how accurate the amplitude of a signal can be measured. The higher the resolution, the more accurate the input signal can be reconstructed.

devices can support multiple resolutions, use tiepie_hw_oscilloscope_get_resolutions() to determine the available resolutions for a device.

Besides native hardware resolutions, also enhanced resolutions can be available for a device. Use tiepie_hw_oscilloscope_is_resolution_enhanced() to determine whether the current resolution is a native hardware resolution or an enhanced resolution.

The resolution can be set manually, but can also be set automatically, when auto resolution mode is enabled.

◆ tiepie_hw_oscilloscope_get_resolutions()

TIEPIE_HW_API uint32_t tiepie_hw_oscilloscope_get_resolutions	(	tiepie_hw_handle	handle,
		uint8_t *	list,
		uint32_t	length
	)

Get an array with the supported resolutions of the specified oscilloscope.

The caller must assure that the array is available and that enough memory is allocated.

Parameters

[in]	handle	A device handle identifying the oscilloscope.
[out]	list	A pointer to an array to contain the supported resolutions, or `NULL`.
[in]	length	The number of elements in the array.

Returns: Total number of supported resolutions, or 0 when unsuccessful.

Status values

TIEPIE_HW_STATUS_INVALID_HANDLE	The handle is not a valid oscilloscope handle.
TIEPIE_HW_STATUS_OBJECT_GONE
TIEPIE_HW_STATUS_LIBRARY_NOT_INITIALIZED
TIEPIE_HW_STATUS_SUCCESS

Example: uint8_t Resolution_count = tiepie_hw_oscilloscope_get_resolutions(h_device, NULL, 0);

uint8_t* Resolutions = malloc(sizeof(uint8_t) * Resolution_count);

Resolution_count = tiepie_hw_oscilloscope_get_resolutions(h_device, Resolutions, Resolution_count);

printf("Scp_get_resolutions:\n");

for(i = 0 ; i < Resolution_count ; i++)

printf("- %u bits\n", Resolutions[ i ]);

free(p_resolutions);

tiepie_hw_oscilloscope_get_resolutions
TIEPIE_HW_API uint32_t tiepie_hw_oscilloscope_get_resolutions(tiepie_hw_handle handle, uint8_t *list, uint32_t length)
Get an array with the supported resolutions of the specified oscilloscope.

◆ tiepie_hw_oscilloscope_get_resolution()

TIEPIE_HW_API uint8_t tiepie_hw_oscilloscope_get_resolution ( tiepie_hw_handle handle )

Get the current resolution of the specified oscilloscope.

Parameters

[in] handle A device handle identifying the oscilloscope.

Returns: The current resolution in bits, or 0 when unsuccessful.

Status values

TIEPIE_HW_STATUS_INVALID_HANDLE	The handle is not a valid oscilloscope handle.
TIEPIE_HW_STATUS_OBJECT_GONE
TIEPIE_HW_STATUS_LIBRARY_NOT_INITIALIZED
TIEPIE_HW_STATUS_SUCCESS

◆ tiepie_hw_oscilloscope_set_resolution()

TIEPIE_HW_API uint8_t tiepie_hw_oscilloscope_set_resolution	(	tiepie_hw_handle	handle,
		uint8_t	value
	)

Set the resolution of the specified oscilloscope.

Parameters

[in]	handle	A device handle identifying the oscilloscope.
[in]	value	The required resolution in bits.

Returns: The actually set resolution in bits, or 0 when unsuccessful.

Remarks: Changing the resolution may affect the sample rate, record length and/or channel trigger enabled.; Setting the resolution will set auto resolution mode to TIEPIE_HW_ARM_DISABLED.

Status values

TIEPIE_HW_STATUS_INVALID_VALUE
TIEPIE_HW_STATUS_INVALID_HANDLE	The handle is not a valid oscilloscope handle.
TIEPIE_HW_STATUS_OBJECT_GONE
TIEPIE_HW_STATUS_LIBRARY_NOT_INITIALIZED
TIEPIE_HW_STATUS_SUCCESS

◆ tiepie_hw_oscilloscope_is_resolution_enhanced()

TIEPIE_HW_API tiepie_hw_bool tiepie_hw_oscilloscope_is_resolution_enhanced ( tiepie_hw_handle handle )

Check whether the currently selected resolution is enhanced or a native resolution of the hardware.

Parameters

[in] handle A device handle identifying the oscilloscope.

Returns: TIEPIE_HW_BOOL_TRUE if the current resolution is enhanced, TIEPIE_HW_BOOL_FALSE otherwise.

Status values

TIEPIE_HW_STATUS_INVALID_HANDLE	The handle is not a valid oscilloscope handle.
TIEPIE_HW_STATUS_OBJECT_GONE
TIEPIE_HW_STATUS_LIBRARY_NOT_INITIALIZED
TIEPIE_HW_STATUS_SUCCESS

Since: 1.0
