Abstract :
A microwave sweep oscillator has been developed which sweeps the range of 8,500-9,500 mc. The RF amplitude over this band is maintained constant to within ± 0.1 db by means of a ferrite modulator unit connected in an amplitude-stabilizing feedback circuit. In addition to providing amplitude control, the ferrite unit also provides amplitude modulation at 1,000 cps of the swept cw source. The generator sweeps the band in about 1.5 seconds, making practical the presentation of network transmission characteristics on an oscilloscope.
