High-frequency generator G4-78 (G478, G4 78)
High-frequency generator G4-78 is designed to control, inspection and investigation of the parameters of radio and antenna-feeder devices.
When using the internal display unit can control power RF power oscillations in the range 10 -4 W-1, 5 ∙ 10 -3 Watt.
The presence of internal modulation of the "meander" enhances the sensitivity of the measurements in the path.
Provided for in the instrument signal generator is a high-G4-78 mode outside of MI allows it to check and adjust the pulse of microwave receivers and different pulse microwave devices.
In FM mode, the function generator may sweep (with small outside swing).
