A plurality of radiant energy sources are alternatively pulsed in accordance with programmable pulsing sequences to permit testing of guided homing seekers and the like. A trigger selector is provided for each source and takes the form of a programmable counter. A source selector receives externally supplied trigger pulses and applies them to one trigger selector until the pre-programmed count is reached, during which time the source associated with that trigger selector is actuated by each pulse. When the pre-programmed count is reached the source selector feeds the trigger pulses to a second trigger selector and to a second source associated with that trigger selector. When the separately programmed count on the second trigger selector is reached, the source selector transfers the trigger pulses back to the first source and trigger selector circuit. The cycle continues in this manner, alternatively supplying trains of trigger pulses to the radiant energy sources. Conveniently, the head encompassing member is in the form of a head band which in itself constitutes said means for holding said temple members against the wearers temples. Author
