PRODUCT INTRODUCTION

The JQVT-9000 series of digital vibration controllers are cost-effective controllers that provide efficient solutions for 2-channel to multi-channel data acquisition and signal analysis. The series of controllers use international advanced DSP framework and algorithm, 32-bit floating point 450 MHz DSP processor, high performance 24-bit ADC, up to 135dB dynamic range, ensuring data acquisition accuracy. The controller and the host computer are connected via a high-speed standard Ethernet, plug and play, eliminating the need to install drivers. The advanced floating design and conduction fanless cooling technology greatly reduce the system noise floor and reduce various introduced interference. The analysis software based on Windows graphical interface is easy to use and easy to use.

PRODUCT ADVANTAGES  

High reliability and high precision

The closed-loop control is realized by the DSP processor. The PC is independent of the control loop, ensuring the real-time and high-efficiency of the control system, and responding to changes in the test system in a timely and rapid manner to ensure the reliability of the control.Each input channel has a 24-bit resolution ADC, low noise hardware design, and built-in analog anti-aliasing and 160dB/Oct digital anti-aliasing filters to ensure high control accuracy.

Powerful functions

Twelve major functions: sinusoidal, resonant search and dwell, random, sinus plus random, random plus random, sine plus random plus random, multiple sine, typical shock, shock response spectrum, transient shock (seismic wave simulation), road spectrum Twelve functions such as simulation and random impact.

Special features: At the same time, in order to adapt to a variety of applications, Yiheng Technology has also developed kurtosis control, channel limit spectrum control, step sine, shock response spectrum analysis of impact signals, support for TEDS sensors and other functions to meet customer needs. demand.

High performance

The stochastic control dynamic range is greater than 90 dB;
The sinusoidal controllable frequency range can be up to 10000 Hz, and the random controllable frequency range can be up to 18750 Hz;
Random test analysis of the number of lines up to 6400 lines;

Input coupling convenience

Input channel of BNC interface, plug and play;
The vibration controller features a variety of signal conditioning and input coupling methods, each with a separate voltage and charge amplifier that supports IEPE, voltage, charge, and TEDS sensors.

High security

More than 20 safety inspection and interlock settings for open-loop detection of control signals, RMS interruption, over-limit line inspection, drive limit, shaker limit, emergency stop button, etc., to ensure maximum testers, test pieces and vibration The security of the equipment.
Channel rms/peak interrupt function, whether it is a control channel or a monitoring channel, each input channel can be independently set with different interrupt values. During the test control process, once the input exceeds the interrupt value, the test is immediately interrupted, effectively protecting the shaker system and the test piece from damage.

Easy for  operation

- PC software is based on Windows operating system, graphical interface, easy to learn;
- Rich window, cursor type, font, color, etc. can be easily modified;
- The sinusoidal function has an AVD window that simultaneously displays the sweep spectrum of acceleration, velocity and displacement;
- Professional test reports can be automatically generated after the test is completed, the format supports WORD, PDF and direct printing;
-Using USB2.0 interface technology to facilitate communication with the computer
