Unit Oscillators: ”[These]Unit Oscillators are general-purpose radiofrequency power sources covering the ranges of 250 to 960 Mc and 180 to 600 Mc, respectively. These members of the convenient Unit Instrument line can be used to drive bridges, slotted lines, impedance comparators, and other measuring equipment. Used with a volt-meter and attenuator, they provide accurately known output voltages for the testing of receivers.
