PROGRAMMABLE_FREQUENCY_FREE_RUNNING_MULTIVIBRATOR

This is the simplest of any programmable oscillator circuit, since only one stable timing capacitor is required. The output square wave is about 25 V pk-pk, and has rise and fall times of about 0.5 μs. If a programmable attenuator circuit is placed between the output and the divider network, 16 frequencies can be produced with two HA-200's and still only one timing capacitor.
