* when FFT spectrum analyzer is connected over Ethernet, the system response delay increases by an order of magnitude as compared to USB-connection, and the system might not complete resonating products or shapes with a sudden level drop. The table shows values for FFT spectrum analyzer connected by USB.

Description

of ZET 017-U24 shaker controller

ZET 017-U24 vibration controller represents a software and hardware suite based on FFT spectrum analyzer. ZET017-U is designed for testing specimen, hardware, and other products, which can be exposed to random vibration or harmonic vibration while being transported and operated. These tests mainly involve the following vibration types impacting the specimen:

Vibration controller: automated system

Now you don’t have to spend much time on settings and tests in manual mode. All you need to do is to select the test mode, set the parameters and press “Start” button! Besides, this system is significantly cheaper than foreign counterparts available on the market.

Shaker is controlled by spectral analyzer using ZETLAB VIBRO programs: sinusoidal signal, broadband random vibration, classic impact, vibration impact. In these programs, you can set the test type to be carried out on the shaker stand and to be controlled by FFT spectrum analyzer over the feedback channel.

To affect the specimen with vibration (random or harmonic) similar to that occurring in typical operation environment, the shaker controller provides generation of the control signal for shaker according to the customized level of vibration set by the user, which must be sustained at the reference measurement point. The system sustains the set level automatically, regardless of any external impacts to the item.
