High-frequency signal generator GSM AXIe

The hardware-software complex "High-frequency signal generator GSM AXIe" is designed to generate harmonic sinusoidal signals with analog modulation (AM, FM, PM, IM) or without modulation in the frequency range from DC to 10 GHz.

Complex functions

Reproduction of unmodulated harmonic signals and signals with amplitude, frequency, phase or pulse modulation in the carrier frequency range from 1 kHz to 10 GHz.

The scope of the complex is radio engineering measurements, research and test work in laboratory and production conditions, testing of communications and other telecommunication equipment.

The principle of operation of the generator is based on the formation of a signal (with analog modulation or without modulation) at an intermediate frequency and the subsequent superheterodyne transfer of the intermediate frequency signal to the high frequencies.

Complex composition

Equipment set:

NMVC Up AXIe-0 module, combining the functionality of UPCONVERTER 10GHz and MGKS;

Software bundle:

Management Library (API);
Software control panel.

Design

Structurally, the signal generator is made in the form of one AXIe module NMVC Up AXIe-0, installed in the AXIe chassis.
