Bruel & Kjaer LDS Comet USB Vibration Controller
The Bruel & Kjaer LDS Comet USB Vibration Controller is built for driving a switching power amplifier used with an electrodynamic shaker and provides a force of at least 2.2kN (495 lb). The LDS Comet USB controller is used for conducting vibration tests and analysis. The LDS Comet USB unit supports two input channels and is designed to offer an affordable and flexible solution for basic vibration testing needs. Apply the LDS Comet USB Vibration Controller in R&D and production test applications, such as stress screening. Its test profiles include random, sine, and shock excitations. The LDS Comet USB Vibration Controller combines 24-bit precision with a wide dynamic control range and a fast loop time to provide highly accurate control.
