A constant-current pulse generator is described. The device is equipped with a transistorized constant-current pulse amplitude regulator which is driven by a monostable multivibrator. A feature of the equipment is a panelmounted indicating meter which measures the time duration of the generated pulse. The amplitude of the pulse may be adjusted as a steady-state reading on a panel ammeter. The time duration of the pulse of this equipment may be adjusted from 1 to 3 milliseconds. The amplitude may be changed from 400 to 800 milliamperes. (auth)
