Detailed Description

Functions for starting and stopping the generator and checking its status.

In certain conditions, like when performing a streaming measurement with the oscilloscope, the generator cannot be controlled. Use tiepie_hw_generator_is_controllable() to poll if the generator can be controlled or use a notification.

Use tiepie_hw_generator_get_status() to check the signal generation status.

Before a generator can be used, the hardware must be switched on (enabled) using tiepie_hw_generator_set_output_enable(). When enabled, the generator signal properties can be set. When the generator hardware is enabled, but the generator is not started, the output will be at the currently set Offset. When the generator hardware is disabled, the hardware is switched off, resulting in the instrument using less power.

Output invert is not available for all instruments. Use tiepie_hw_generator_has_output_invert() to check whether output invert is available for your instrument.
