High-frequency signal generator G4-164A (G4164A, G 4164 A, G-4-164-A, G4 164A)
High-frequency signal generator G4-164A is designed to control, configure and test various radio devices operating in manual control mode and in automatic control mode via the public (CPC).
The device can be a source of unmodulated signal and unsized, used as a local oscillator at the frequency of different transformations.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) and Pulse Width Modulation (IM).
High-frequency signal generator G4-164A is designed to work in laboratories and workshops, test agencies, repair shops.
The device is a source of high-frequency signal in the frequency range from 0.1 MHz to 639.999 MHz, running in HK, AM, FM and IM. Installing the required operating mode by using 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 G4-164A 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 is carried out as from an internal source of modulating oscillations and from the outside. Possible modulation of two parameters simultaneously: the frequency and amplitude..
