Hand-held railway interference tester

The utility model relates to a hand-held railway interference tester comprising a monitoring directional antenna, a monitoring host, and a GPS antenna; the monitoring host is connected with the monitoring directional antenna and the GPS antenna through an interface; the monitoring host comprises a reception module, a signal processing module, a GPS module, a display and a lithium battery module. The tester uses software radio technology, and combines signal scanning, spectrum analysis, field intensity measuring, orientation measuring, GPS positioning and data recording functions; the tester is small in size, light in weight, low in power consumption, simple in operation on a touch screen, can conveniently carry out railway line dynamic monitoring and fixed point electromagnetic environment tests, so monitoring area electromagnetic frequency spectrum situation can be handled at any time, thus timely spotting and checking communication interference, and providing practical and effectively technical support and guarantee for railway smooth communication.
