Systems include:Two vibrators with trunnions, fan cooled low-distortion linear amplifier, cables, and hoses where required. A cooling blower is required for the vibrators at any force output of 45 pounds or greater (the B-1 Blower is recommended).
VTS Offers three systems for multiple vibration input testing.
Two of the systems consist of two vibrators and a dual channel amplifier. Separate operation with individual control of the vibrators or series connection with a single control signal is conveniently accomplished. The other system consists of two vibrators series connected and a single channel amplifier.

The significantly simplified fixture approach, which was originally designed for printed circuit board testing, is extremely low in weight and permits the use of smaller vibrators for testing large area lightweight packages of varying sizes and shapes.
The unique design of this VTS multiple vibrator arrangement provides circuit board resonance more nearly approximating actual chassis mounted resonance for more realistic screening.
Includes the DVC-4 Random vibration controller. It permits you to utilize the capabilities of your Pentium computer to perform as a vibration controller. See the Four Channel Digital Controller page for more details. The adjustable base plates are available to accommodate boards ranging in size from 8 to 18 inches or more in length, and up to 15 inches in width.
