ABSTRACT:
A personal computer card which includes four tone generators connected to a radio frequency synthesizer which, in turn, is connected to a 400 MHz hcal rubber coated antenna. Each of the four tone generators may be programmed to generate any one of twenty Interrange Instrumentation Group standard decoder tones which are used for testing the flight termination receivers and decoder in certain weapons systems such as a missile. The standard decoder tones generated by each of the four tone generators are supplied to the radio frequency synthesizer. The radio frequency synthesizer frequency modulates the IRIG tones onto a carrier signal in the flight termination band which is in a range from 400 MHz to 440 MHz. The modulated radio frequency signal is then supplied to the antenna for transmission to the weapons system being tested.
