High-frequency signal generator G4-124

Also, this device can be called: G4 124, G4124, G-4124, G 4124.

G4-124 signal generator is designed for high power RF energy measuring lines, directional couplers, high bridges, antennas, and to configure and test the resonant frequency gauges, filters, input circuits, etc.

G4-124 generators are in the form of portable devices, and may be used in a laboratory, factory or in the field.
