Testing Radio Receivers On The Assembly Line

1930 Radio Station Assistant

Standard-Signal Generator lias proved to be a most useful instrument for these tests. Figure 1 on the next page shows them in the final production line at the Roister Radio Corporation's factory in Newark, New Jersey. In order to take care of the peak production from this plant, ten test positions are necessary. Each one has its Type 601-A Standard-Signal Generator mounted upon a cabinet containing two loud-speakers one is a stand-by in case of trouble and an output meter. The completely...

Variable Inductors For Bridge Measurements

IT is a peculiarity of bridge measure- raents practice that, while variable continuously adjustable capacitance standards are almost universally used in preference to fixed standards, a general preference for fixed inductance standards over variable standards has prevailed. There are, as a matter of fact, many cases where measurement methods can be improved by the use of a continuously adjustable inductor or variometer. The use of such an instrument permits the use of equal arm bridges for...
