* Usable frequency range. The usable frequency range is defined as the range in which a sine sweep can be performed without abort. The range quoted indicates that the expander is controllable up to this frequency. Note that a highly resonant payload, particularly one of large mass, may limit the usable frequency and introduce new resonances into the system. For further information and advice on the usable frequency range please contact your local LDS sales office.

All features listed are standard. Please contact LDS for advice on the optimum specification to meet your system needs. Specifications are correct at time of going to print. LDS reserves the right to amend specifications without prior notice.
