collection/hardware_properties HardwareProperties Fixed properties of hardware components used in the experimental setup. There are two sections for describing hardware components: the "HardwareProperties" and the "HardwareSettings" section. While the HardwareProperties describe the fixed properties of the hardware that can not be changed, the HardwareSettings section describes the actual, adjustable, parameters of the hardware that may change with each recording or dataset. For example, the sample rate of an data-acquisition board or the settings of a filter. In each of these two sections there are subsections for each device that correspond to the class of the device like data-acquisition, amplifier, etc. Some properties are common for any type.
