The universal pulse generator UPG can generate impulse trains up to 9999 pulses or a continguous clock signal. Frequency range 5 mHz to 50 kHz. It has both a CMOS output with adjustable level (2..5 Volts) and an open collector output. Impulse trains are startet by an applied trigger signal or manually by pressing a button. The instrument is powered from a 230 VAC mains adapter (included).
