Abstract
Abstract Television test apparatus for testing television chassis is shown. The test apparatus incorporates a cathode ray tube and deflection components therefor together with coupling apparatus for coupling the deflection signals from the chassis under test to the yoke in the test apparatus. The coupling apparatus includes an impedance transformer such as an autotransformer and switch or jumper modules for connecting the horizontal deflection windings of the yoke in either series or parallel and to the autotransformer for providing proper impedances to the chassis under test.
