Special Features:

Installed in place of the standard test fixture plug in, it provides accurate calibration voltages and currents for the horizontal and vertical deflection circuits and accurate loads for the collector supply and step generator circuits through the external input and output lines at the test fixture; c/o vertical, display offset, horizontal and step generator switches of the 576 have matching switches on the calibrator for direct reading, comparison style adjusting and checking, using the 576's own display; totally dependent on the 576 for regulated low voltage power supplies and ac line voltage

Properties:

Two or more different types of items, having a common mounting or mounted on each other, which together form a portion of a calibrator, but which in itself is not a complete functioning item and cannot be assigned a more definite item name.
