About This Product
Ramp and pedestal triggering are each set with their own pair of potentiometers, so students can move the SCR firing point through the full-wave rectified cycle and watch the effect at the panel sockets. Because the isolation transformer separates the circuit from the mains, oscilloscopes and other instruments that are not isolated are kept from damage.
