Description: Abstract: The use of direct digital synthesis techniques to create a new method of frequency sweep signal. The use of counters and phase accumulator to achieve the waveform memory addressing, resulting in a frequency sweep signal sequence. The sequence through the number- analog converter and low pass filter, to produce a frequency sweep signal. Was synthesized frequency sweep signal the start frequency, stop frequency and sweep time can be arbitrarily set according to need, and can achieve precise control of the three.
