ARBOR SCIENTIFIC Sine Wave Generator 110 V 60 Hz

This precision Sine Wave Generator is an excellent tool for generating waves with speakers for sound or with our Mechanical Wave Driver (P7-1000) for standing waves. It allows control for both the frequency and amplitude of the sine wave output. Students can observe the quantum nature of standing wave patterns as the Sine Wave Generator jumps from one resonant frequency to the next.The Sine Wave Generator allows both the frequency (1-400 Hz/1 Hz resolution and 10-4000 Hz/10 Hz resolution) and amplitude of the sine wave output to be varied. Our Mechanical Wave Accessories Bundle (P7-1500) offers everything you need to get the most out of the Sine Wave Generator. Power supply – 1 A max.110 V; 60 Hz; US Plug Type B; 5.4″ L x 5.14″ W x 3.62″ H
