Detailed Description

Functions for controlling the phase of a generator.

The phase defines the starting point in the period of the signal that is generated, as well as the ending point. The phase of a generator can be set between a minimum and a maximum value. Use tiepie_hw_generator_get_phase_min() and tiepie_hw_generator_get_phase_max() to get the phase limits.

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

Phase is not available on all instruments and all signal types. Use tiepie_hw_generator_has_phase() to check whether phase is available for your instrument and for the currently set signal type.

By default the phase is set to: 0.

◆ tiepie_hw_generator_get_phase()

TIEPIE_HW_API double tiepie_hw_generator_get_phase ( tiepie_hw_handle  handle)

Get the current signal phase of a specified generator.

Parameters
[in]handleA device handle identifying the generator.
Returns
The currently set signal phase, a number between 0 and 1.
Status values
TIEPIE_HW_STATUS_NOT_SUPPORTED The generator does not support phase for the current signal type.

◆ tiepie_hw_generator_set_phase()

TIEPIE_HW_API double tiepie_hw_generator_set_phase ( tiepie_hw_handle  handle,
double  value 
)

Set the signal phase of a specified generator.

Parameters
[in]handleA device handle identifying the generator.
[in]valueThe requested signal phase, a number between 0 and 1.
Returns
The actually set signal phase, a number between 0 and 1.
Status values
TIEPIE_HW_STATUS_VALUE_CLIPPED The requested phase is outside the valid range and clipped to the closest limit.
TIEPIE_HW_STATUS_VALUE_MODIFIED The requested phase is within the valid range but not available. The closest valid value is set.
TIEPIE_HW_STATUS_NOT_SUPPORTED The generator does not support phase for the current signal type.
TIEPIE_HW_STATUS_NOT_CONTROLLABLE
TIEPIE_HW_STATUS_INVALID_HANDLE The handle is not a valid generator handle.
TIEPIE_HW_STATUS_OBJECT_GONE
TIEPIE_HW_STATUS_LIBRARY_NOT_INITIALIZED
TIEPIE_HW_STATUS_SUCCESS
Remarks
When the generator is active, changing the phase will shortly interrupt the output signal.
When signal type DC or Noise is active, setting phase is not available.
