Detailed Description

Functions for controlling the phase of a demo signal.

The phase defines the starting point in the period of the signal that is generated, as well as the ending point.

The phase is defined as a number between 0 and 1, where 0 defines the beginning of the period (0°) and 1 defines the end of the period (360°).

Several of the demo signal types support setting the signal phase, but others don't. Use tiepie_hw_oscilloscope_channel_demo_has_phase() to find out whether the selected demo signal type supports setting the phase.

By default the phase is set to: 0.

◆ tiepie_hw_oscilloscope_channel_demo_has_phase()

TIEPIE_HW_API tiepie_hw_bool tiepie_hw_oscilloscope_channel_demo_has_phase	(	tiepie_hw_handle	handle,
		uint16_t	ch
	)

Check whether the currently selected demo signal type supports setting the phase.

Parameters

[in]	handle	A device handle identifying the oscilloscope.
[in]	ch	The channel number identifying the channel, `0` to `tiepie_hw_oscilloscope_get_channel_count() - 1`.

Returns: TIEPIE_HW_BOOL_TRUE if setting the phase is supported, TIEPIE_HW_BOOL_FALSE if not.

Status values

TIEPIE_HW_STATUS_INVALID_CHANNEL
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_channel_demo_get_phase()

TIEPIE_HW_API double tiepie_hw_oscilloscope_channel_demo_get_phase	(	tiepie_hw_handle	handle,
		uint16_t	ch
	)

Get the currently selected demo signal phase of a specified demo oscilloscope channel.

Parameters

[in]	handle	A device handle identifying the oscilloscope.
[in]	ch	The channel number identifying the channel, `0` to `tiepie_hw_oscilloscope_get_channel_count() - 1`.

Returns: The currently set demo signal phase, a number between 0 and 1.

Status values

TIEPIE_HW_STATUS_NOT_SUPPORTED	The currently selected demo signal type does not support getting the demo signal phase.
TIEPIE_HW_STATUS_INVALID_CHANNEL
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_channel_demo_set_phase()

TIEPIE_HW_API double tiepie_hw_oscilloscope_channel_demo_set_phase	(	tiepie_hw_handle	handle,
		uint16_t	ch,
		double	value
	)

Set the demo signal phase of a specified demo oscilloscope channel.

Parameters

[in]	handle	A device handle identifying the oscilloscope.
[in]	ch	The channel number identifying the channel, `0` to `tiepie_hw_oscilloscope_get_channel_count() - 1`.
[in]	value	The requested demo signal phase, a number between `0` and `1`.

Returns: The actually set phase.

Status values

TIEPIE_HW_STATUS_NOT_SUPPORTED	The currently selected demo signal type does not support setting the demo signal phase.
TIEPIE_HW_STATUS_INVALID_VALUE	The requested signal phase is not valid.
TIEPIE_HW_STATUS_INVALID_CHANNEL
TIEPIE_HW_STATUS_INVALID_HANDLE	The handle is not a valid oscilloscope handle.
TIEPIE_HW_STATUS_OBJECT_GONE
TIEPIE_HW_STATUS_LIBRARY_NOT_INITIALIZED
