Description

Technical Field

[0001] The utility model relates to the technical field of radio monitoring, in particular to a multi-carrier dual-mode signal source device. Background Art

[0002] Radio monitoring refers to the activities of detecting, searching, intercepting radio signals within the radio management area, and analyzing, identifying, monitoring and obtaining technical information such as their technical parameters, working characteristics and radiation positions of the radio signals. It is an important means and basis for the effective implementation of radio management and an important branch of radio spectrum management.

[0003] There are mainly two types of radio signal sources on the market: one is a general radio frequency signal source, which connects the frequency of the main oscillator source and the frequency of the reference frequency source through a phase-locked loop, supports various modulation methods such as frequency modulation (FM), phase modulation (PM) and amplitude modulation (AM), etc., to meet the needs of different communication systems, and is used to calibrate radio frequency radio measurement instruments such as spectrum analyzers and modulation analyzers. The other is a single-mode signal source. There are signal sources with single-mode signal types on the market, including signal formats such as FM, FSK, LORA, etc. The signal is generated by a single-mode signal generation module and a single type of radio signal is output through a power amplifier.

[0004] The existing radio frequency signal sources have the following problems:

[0005] 1. The application scenarios are limited. The product form is a radio measurement instrument, which is large in volume and weight, so it is mostly used in relatively fixed scenarios such as laboratories.

[0006] 2. The existing radio frequency signal source device is a general wideband multi-modulation signal source, which is difficult to use and requires relatively professional technical personnel to operate.

[0007] Therefore, the existing technology has defects and needs to be improved. Content of the Utility Model

[0008] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide a multi-carrier dual-mode signal source device.

[0009] The technical solution of the utility model is as follows: A multi-carrier dual-mode signal source device is provided, including: an ARM industrial control board, a spread spectrum module, an analog signal generation module, and a power supply module. The power supply module supplies power to the ARM industrial control board, the spread spectrum module, and the analog signal generation module. The ARM industrial control board is connected to the spread spectrum module and the analog signal generation module respectively through LAN.

[0010] Furthermore, an on-board switch is built into the ARM industrial control board. A LAN connection port is provided on the on-board switch. The on-board switch is electrically connected to the spread spectrum module and the analog signal generation module through a connecting wire connected to the LAN connection port.

[0011] Furthermore, the ARM industrial control board is built with a LAN connection module and a WIFI module.

[0012] Furthermore, the frequency range of the analog signal generated by the analog signal generation module is 100 MHz - 8000 MHz, the modulation bandwidth is 25 KHz, and multi-carrier modulation is supported.

[0013] Furthermore, the frequency range of the spread spectrum signal generated by the spread spectrum module is 130 MHz - 1500 MHz.

[0014] Furthermore, the power supply module includes: a lithium battery, a DC-DC conversion circuit, and a switch button module. The lithium battery and the DC-DC conversion circuit are respectively connected to the switch button module. The switch button module switches the power supply states of the DC-DC conversion circuit, the spread spectrum module, and the analog signal generation module. The DC-DC conversion circuit is electrically connected to the ARM industrial control board.

[0015] With the above solution, the multi-carrier dual-mode signal source device provided by the present utility model has a simple composition and a small device volume. By methods such as resident control software in the ARM industrial control board, hardware modules generating radio frequency signals, and lithium battery power supply, portable multi-carrier dual-mode signal transmission is realized. Different frequency range analog signals and spread spectrum signals are respectively sent through the analog signal generation module and the spread spectrum module to meet the requirements of multi-carrier dual-mode signal transmission.
