The LW126.138-13 system offers the maximum force available from the light-weight armature ET-126 shaker, without forced air cooling. This compact desktop system is perfectly suited for general purpose testing of small transducers as well as electrical and mechanical assemblies. The ET-126 also satisfies most high frequency test requirements with operation up to 8,500 Hz.A voltage-proportional-to-output-current output signal is provided for modal test and other applications requiring force monitoring. The combination of high acceleration, high frequency range as well as high force with good load carrying ability and desktop convenience, makes this a popular choice for medium acceleration level testing
