This is the simplest of any programmable oscil lator circuit, since only one stable timing capacitor is required. The output square wave is about 25 V pk-pk, and bas rise and fall times of about 0.5 p,s.

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.
