The generation waveforms is accomplished using: a computer, two random access memories (RAM), a digital-to-analog converter (DAC), two modulators, two oscillators, and a multiplier. The computer inputs a set of digital waveforms and a first control signal into the first RAM which, when directed, conducts them to the DAC. The DAC converts the digital waveform to an analog waveform, and conducts the analog waveform and the first control signal to the first modulator. The first modulator produces an output signal by single sideband (SSB) modulating an intermediate frequency carrier from the first oscillator with the analog waveform when directed to modulate by the first control signal, and outputs the analog waveform otherwise the multiplier increases the bandwidth of signals from the first modulator by multiplying its output signal. The output of the multiplier is received by the second modulator. The second modulator is a biphase modulator which produces an output signal by biphase modulating a radio frequency carrier signal from the second oscillator with the signal from the multiplier when directed to modulate by a second control signal received from the second RAM, and outputting the signal from the multiplier otherwise.
