A sweep generator circuit for use with a cathode ray oscilloscope. It provides for a high duty-cycle by eliminating the discharge and recovery time of a conventional sweep generator circuit. This is accomplished by alternately charging and discharging the timing capacitor at equal rates, forming linear up and down ramp signals. Then, by amplifying the ramp signals along with synchronously reversing the polarity of the amplified down ramp signals, using electronic switching, identical unidirectional sweeps are produced during both charging and discharging times of the timing capacitor.
