Detailed Description

The Time property determines how long a specific condition must last for the channel trigger to respond.

The number of time properties depends on the currently selected trigger kind and currently selected trigger condition. Use tiepie_hw_oscilloscope_channel_trigger_get_time_count() to determine the number of trigger time properties for the currently set trigger kind and condition.

The trigger time can be affected by changing the sample rate.

The trigger time is set as a value in seconds. By default time[0] is set to 1 ms.

tiepie_hw_oscilloscope_channel_trigger_get_time_count()

TIEPIE_HW_API uint32_t tiepie_hw_oscilloscope_channel_trigger_get_time_count	(	tiepie_hw_handle	handle,
		uint16_t	ch
	)

Get the number of trigger times for the current trigger kind and trigger condition.

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 number of available trigger times for the current trigger kind and condition.

Status values

TIEPIE_HW_STATUS_NOT_SUPPORTED	The indicated channel does not support trigger with the current settings.
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

Returns

The currently set trigger time value, in seconds.

Status values
