Manufacturer:NS Description:Basic waveforms and dc operating voltages for the test set are derived from a power supply section comprising a posi- tive and a negative rectifier and filter a test set voltage regulator a test circuit voltage regulator and a function gen- erator The dc supplies will be discussed in the section deal- ing with detailed circuit description The waveform generator provides three output functions a g19V square wave a b 19V to a 19V pulse with a 1% duty cycle and a g5V triangular wave The square wave is the basic waveform from which both the pulse and triangular wave outputs are derived The square wave generator is an operational amplifier con- nected as an astable multivibrator This amplifier provides an output of approximately g19V at 16 Hz This square wave is used to drive junction FET switches in the test set and to generate the pulse and triangular waveforms The pulse generator is a monostable multivibrator driven by the output of the square wave generator This multivibrator is allowed to swing from negative saturation to positive satu- ration on the positive going edge of the square wave input and has a time constant which will provide a duty cycle of approximately 1% The output is approximately b19V to a 19V |
