Physi ac-operated version these factors have been cally, the new oscillator is small enough and kept very small, too. In addition, since the cir light enough to be held easily in one hand. cuit is fully transistorized, the new oscillator Electrically, it operates over the frequency is virtually insensitive to vibration and shock, SEE ALSO range from 5 cps to making it a very stable and rugged precision "New high-power 500 kc in 5 ranges. instrument indeed.
