Compact and powerful, this exciter is versatile and reliable, built for challenging modal applications, SISO (Single Input Single Output) and SIMO (Single Input Single Output) for mechanical components such as engines. Input Multiple Output) trials, as well as MISO (Multiple Input Single Output) and MISO (Multiple Input Single Output) trials for large structures. It provides pulsed, sinusoidal and random signals, as well as a wide frequency range (DC - 5000Hz), displacement up to 25.4 mm (1 inch), and greatly improved low frequency performance.
