Abstract:BD 1 type signal generator has been developed in order to improve technicalfunction of pulse calibrater and satisfy applied request for telemetering seismic network tocalibrate section by section.The equipment applies more advanced technics of single chip processor,and can generatesine wave signal with 18 frequency for calibration to need by making use of digital synthesis.
Keywords:calibration  signal generator  frequency error  amplittide error  distortion ratio
