The first of these, the which were designed with direct-reading RF subject of this article, operates over the band controls in place of the indirect readout from 800 to 2400 megacycles and provides an arrangements used previously. During the RF power output that is virtually flat (within years since, these generators have become ±0.5 db) over this entire range. The flat output widely known and used in the microwave is obtained by an automatic internal leveling field1'2. system and eliminates the need for readjusting This long experi the output power at each change of frequency, SEE ALSO: ence with microwave thus facilitating many measurements.
