Overview
T3700A is an interference signal generator to be used in the satellite navigation test field. It is developed based on the VSG platform and has rich interference signal generation functions, broad frequency coverage and wide power regulation range. It can be used to generate various kinds of suppressing and deception interference, such as CW signals, frequency sweep signals, analog modulation signals, digital modulation signals, broadband noise and other kinds of customized interference. It is mainly applied in the antiinterference performance test of the GNSS and other fields.
