High-frequency signal generator G4-129 (G4129, G4 129)
High-frequency signal generator G4-129 is designed for setting, adjustment and testing of various wireless devices UHF.
- Mode of unmodulated oscillations;
- Mode of amplitude modulation of the internal sinusoidal signal (only a G4-128);
- Mode of amplitude modulation of the external sinusoidal signal (only a G4-128);
- Mode of the internal frequency modulation sinusoidal signal;
- External mode frequency modulation sinusoidal signal;
- Mode of internal modulation meander 1kHz;
- Mode of external pulse modulation;
- Synchronizing the oscillator frequency is an external synchronizer mode unmodulated oscillation.
Operation is a high frequency signal generator G4-129 is based on the principle of forming the output signal in the frequency range up to 310MGts 1200MGts signal from the master oscillator in the range from 600MHz to 1200MGts.The output signal of the master oscillator is fed to two channels: the channel forming the output signal generator and a channel built-in electronic display frequency.
All types of modulation (FM, MI) implemented in the signal generator G4-129. The amplifier output power is provided by non-calibrated at least 0, 5 W in CW mode, FM, and IM.
Adjusting the output signal generator G4-128 by adjusting the output power signal generator G4-129.
