Sawtooth output of UJT varies sinusoidal output frequency of Optical Electronics 3370 voltage-to-frequency transducer, as required for checking frequency response of active and passive networks. R1 determines sweep width. Center frequency of sweep output can be changed by adding voltage to sawtooth or adjusting 3370. Sweep speed can be increased by reducing value of 1-μF tantalum capacitor.- Sweep Generator Using a Voltage-to-Frequency Transducer, Optical Electronics, Tucson, AZ, Application Tip 10059.
