  • Measurement test instrument and associated voltage management system for accessory device
    Patent number: 6829547
    Abstract: A measurement test instrument voltage management system for an accessory device has a accessory device interface that provides a voltage to a memory device in the accessory device. A sensing signal is generated when the accessory device is connected to the interface that causes an interrupt signal to be coupled to a controller. The controller retrieves accessory device data stored in the device memory via the interface and determines if the connected accessory device is a valid device capable of being supported by the measurement test instrument and voltage power requirements for the accessory device. The controller generates an enable signal for a valid and supported device that is coupled to a voltage switching circuit. The voltage switching circuit generates at least a first output voltage based on the voltage power requirements that is coupled to the accessory device via the interface to provide power to the accessory device.
