The 470A500 High Power Signal Generator can be used for any application which requires a stable source of controllable r-f power higher than that obtainable from milliwatt-level signal generators. Both the power output and the grid and cathode currents are monitored on front-panel meters. The instrument is capable of either CW, internal or external square-wave, or pulse-modulated outputs. A monitor jack provides a signal approximately 35 dB down from the main output which is particularly useful for wave form analysis and frequency calibration. Covers 200 to 500MHz frequency range Up to 70 W power output Built-in 1 kHz modulation monitoring circuits for power, grid, and cathode circuits Excellent frequency and power stability
