Detailed Description

Functions for controlling the trigger level mode.

The trigger level can be set in two different ways, indicated by the trigger level mode:

• TIEPIE_HW_TLM_RELATIVE, the trigger level is set as a floating point value between 0 and 1, corresponding to a percentage of the full scale input range.
• TIEPIE_HW_TLM_ABSOLUTE, the trigger level is set as a floating point value, clipped by the full scale input range.

When trigger level mode is set to TIEPIE_HW_TLM_RELATIVE and auto ranging of the channel is enabled, the trigger level will remain at the same percentage when the input range changes, resulting in a different absolute voltage.

When trigger level mode is set to TIEPIE_HW_TLM_ABSOLUTE and auto ranging of the channel is enabled, the trigger level will remain at the same absolute voltage level when the input range changes. The input range will not auto range to a range that is smaller than the selected trigger level.

By default the trigger level mode is set to TIEPIE_HW_TLM_RELATIVE.
