Detailed Description

Functions to control the offset of a demo signal.

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

By default the offset is set to: 0 Volt.

◆ tiepie_hw_oscilloscope_channel_demo_has_offset()

TIEPIE_HW_API tiepie_hw_bool tiepie_hw_oscilloscope_channel_demo_has_offset	(	tiepie_hw_handle	handle,
		uint16_t	ch
	)

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

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 offset 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_offset()

TIEPIE_HW_API double tiepie_hw_oscilloscope_channel_demo_get_offset	(	tiepie_hw_handle	handle,
		uint16_t	ch
	)

Get the currently selected demo signal offset 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 offset, in Volt.

Status values

TIEPIE_HW_STATUS_NOT_SUPPORTED	The currently selected demo signal type does not support getting the demo signal offset.
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_offset()

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

Set the demo signal offset of a specified demo oscilloscope channel, in Volt.

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 offset, in Volt.

Returns: The actually set offset, in Volt.

Status values

TIEPIE_HW_STATUS_NOT_SUPPORTED	The currently selected demo signal type does not support setting the demo signal offset.
TIEPIE_HW_STATUS_INVALID_VALUE	The requested signal offset 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
TIEPIE_HW_STATUS_SUCCESS
