The invention discloses a comprehensive parameter field measurement device for a signal source. The device comprises a radio frequency front-end module, a frequency measurement module, an attenuation measurement module, a modulation measurement module, a spectrum purity measurement module and a display control module. The input end of the radio frequency front-end module is used as the input end of the signal to be measured of the comprehensive parameter field measurement device for the signal source. The output end of the radio frequency front-end module is connected with the input ends of the frequency measurement module, of the attenuation measurement module, of the modulation measurement module, of the spectrum purity measurement module and of the display control module respectively. The input ends of the frequency measurement module, of the attenuation measurement module, of the modulation measurement module, of the spectrum purity measurement module and of the display control module are all connected with the input end of the display control module. The comprehensive parameter field measurement device for the signal source has the advantages of realizing the measurement of each technical indicator of the signal source.
Description
technical field [0001] The invention relates to radio measuring instruments. More specifically, it relates to a field measurement device for comprehensive parameters of a signal source. Background technique [0002] The signal source is the most widely used radio instrument, and it is widely used in the field of radio communication scientific research and testing, as well as the active equipment of the army (radar, missile, aircraft and navigation satellite, etc.), testing grounds, shooting ranges and many other occasions. Its performance indicators have an important impact on each application system. However, under normal circumstances, the test environment conditions in the proving ground and shooting range are relatively harsh, and it is often carried out outdoors. The temperature and humidity environment and the voltage of the power supply fluctuate greatly, and the zero-ground voltage can sometimes reach nearly 20VPP. These factors are easy Cause irreversible and seri...
