Data Acquisition Interface/Power Supply (9507-3)
The Data Acquisition Interface converts the received signal coming from the Antenna Positioner into a digital signal which can be used by the computer.
It also routes the shaft encoder signals coming from the Antenna Positioner to the computer. The Data Acquisition Interface also provides the signals required to control the drive motor and the variable attenuator in the Antenna Positioner.
A BNC connector and a multi-pin connector allow connection of the Data Acquisition Interface to the Antenna Positioner.
The Power Supply, which provides regulated DC power to the Data Acquisition Interface, has a Lab-Volt standard unregulated DC power bus for supplying power to other compatible modules through its top panel connector.
The unregulated DC power bus also supplies power to the Antenna Positioner through a multi-pin connector mounted on the front panel of the module.
The Power Supply also provides AC power to the drive motor in the Antenna Positioner through this multi-pin connector. An illuminated power switch allows the Power Supply to be turned on and off.
