Keysight-Agilent 628A

The 628A SHF Signal Generator cover 15 to 21GHz frequency range. Carrier frequency is set and read directly on the large tuning dial. No voltage adjustment is necessary during tuning because the klystron repeller voltage is tracked with frequency changes automatically. Oscillator output is also set and read directly, and no frequency correction is necessary throughout operating range. A frequency logging scale permits frequency to be reset within 0.1%. 10 mW to 1 pW output, FM or pulse modulation.
