Driver for Rohde Schwarz NGX Power Supplies using the VISA interface.

The desired channels have to configured using the channel index (starting from 1) and a user-friendly channel name. For each channel, the HERO gains properties channel_name_ current, voltage, power and status. In addition, current and voltage can be set using the property.

Querying can also occur for the configured number of channels simultaneously by using the class-level properties.

All properties are provided as observable data.
