Signal Generator
- BWO source
- Reference output power
- GPIB, USB, RS-232 programmable
The G4-1XXM series Signal Generator is general-purpose source for testing and verification of microwave equipment in industrial and laboratory conditions. The instrument provides high accuracy millimeter-wave signal level in wide attenuation range and can be integrated in manual or automatic measurement systems.
