Problems solved by technology

However, the ultrashort wave radio station needs to be measured before it is put into use to ensure that its performance indicators meet the requirements, but now it is mainly measured during actual use. This measurement method is not easy to operate and control, and the measurement results are not accurate, so it cannot meet some high-demand fields. needs

Abstract

The present invention discloses an ultra-short wave radio terminal testing device which comprises a controller, a bus backplane, a calibrator and an ultra-short wave radio terminal. The bus backplane is connected to the controller and is also connected to a spectrum analysis module, a vector signal module and an RF switch matrix module at the same time. The RF switch matrix module is also connected to the spectrum analysis module and the vector signal module at the same time. The ultra-short wave radio terminal and the RF switch matrix module are connected through an attenuator. The RF switch matrix module is also connected to a transmitting antenna. The ultra-short wave radio terminal is connected to the controller and a receiving antenna at the same time. The controller is connected to an LCD screen, the calibrator and the ultra-short wave radio terminal. According to the ultra-short wave radio terminal testing device, through the above principle, the closed-loop measurement is used, the measurement process is easy to control, an automatic calibration test can be achieved, test result information is more stable and reliable, and the performance of a produced ultra-short wave radio terminal is more superior.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an ultrashort wave radio terminal testing device. Background technique [0002] Ultrashort wave radio communication equipment with a working wavelength of 10 to 1 meter (frequency of 30 to 300 MHz). Strictly speaking, all relays, scattering machines, and meteor trail communication equipment that work in this band belong to ultrashort wave radio stations. But it usually refers to walkie-talkies, portable, vehicle-mounted (or airborne, ship-borne) radios that are transmitted by ground wave or space wave line-of-sight. It is mainly composed of transceivers, antennas and power supplies. Ultra-short wave radio stations can use AM, FM, SSB and other modulation systems, usually FM-based, and its anti-interference performance is better than AM and SSB. Compared with short-wave radio, ultra-short-wave radio has the advantages of communication frequency bandwidth, large capacity, and stable si...
