Signal generator Spektra 6000

GEN 15 chịu trách nhiệm tạo tín hiệu và bao gồm bảng cơ sở DSP 15 với tối đa hai mô-đun mở rộng. Mô-đun mở rộng thứ hai tùy chọn cho phép triển khai bộ tạo tín hiệu độc lập thứ hai.

The GEN 15 is responsible for signal generation and consists of a DSP 15 base board with up to two expansion modules. The optional second expansion module allows a second independent signal generator to be implemented.

The DSP 15 base board acts as an FPGA-based, flexibly configurable signal processor for real-time signal filtering and control.

The GEN 15 also includes a module for conditioning the output signals for electrical measurement purposes (voltage/charge conversion, precise AC voltage divider and IEPE sensor simulation).

The ANA 15 Q is used for measuring analog AC signals. It transfers the digital measurement data via a backplane to the GEN 15 or CCB 15 module for processing. All ANA 15 modules of a HERO™ work synchronously. Each ANA 15 Q represents one analog input channel.

The module has integrated signal conditioners for IEPE sensors and piezoelectric sensors with charge output. It can receive analog signals from other signal conditioners, which are available as optional modules, via the backplane. The inputs are galvanically isolated.

The PR 15 module is a signal conditioner for sensors that are based on a measurement bridge, e.g. piezoresistive acceleration sensors.

The amplified analog signals are passed to an ANA 15 module, where they are converted to digital measurement data. The allocation of the PR 15 to a corresponding ANA 15 channel is carried out automatically by the HERO™ firmware or by qualified PC software. The sensors are connected by an interface box linked to the PR 15. Resistors can be added in the interface box for adding half-bridges or for adding shunt resistors.
