High-frequency signal generator G4-176 (G4176, G4 176)
 
High-frequency signal generator G4-176 is designed to control, configure and test various radio equipment operating in manual mode and automatic mode control via the public (CPC).
The generator provides a measurement of the amplitude-frequency characteristics of various devices, the actual sensitivity curve and fidelity receivers, running in the unmodulated oscillations (NC), amplitude modulation (AM), frequency modulation (FM) modulation and television (TV).
High-frequency signal generator G4-176 can be a source of unmodulated signal and unsized, used as a local oscillator at the frequency of different transformations.
The generators are designed to work in verification agencies, repair shops, laboratories and workshops.
High-frequency signal generator G4-176 is a source of high-frequency signal in the frequency range from 0.1 MHz to 1020MGts-mode SC, AM, FM and TV.
Set the desired mode of operation is carried out through the keyboard controls on the front panel of the generator. Enter the required values ​​of parameters such as frequency, output voltage, the coefficient of amplitude modulation, frequency deviation shall be made either through the keypad or by means of sensor kvaziplavnoy settings on the front panel of the generator. Established parameters of the device high-frequency signal generator G4-176 can be stored in internal memory for the number assigned to a subsequent call.You can save up to 63 sets of parameters of the generator. These transactions are running embedded micro-processor-based computer N1830VE51 that can significantly reduce energy consumption and improve reliability and manufacturability compared with the base model of the generator.
Modulation of the carrier frequency signal generator unit high-G4-176 is carried out both from an internal source of modulating oscillations from an external (except TV).
Possible modulation of both the two parameters: amplitude and frequency.
