Acquistion card composition

The signal processing flow of each channel is roughly as follows: after the signal is received by the front-end sensor and amplified by the amplifier, it enters the acquisition card through the coaxial cable access channel interface, and the gain of the acquisition card set by the software modulates the signal to ± 10, ± 5V, ± 2V, ± 1V, ± 0.1V, and the adjusted voltage signal enters the analog filter. The whole analog filter circuit consists of three high passes and three high passes Low pass consists of four order Butterworth filters with nine filter bands that can be set by software to filter the signal and then enter AD conversion chip. The ad chip is 10m16bit, and the sampling rate can be set by software to convert the voltage signal into digital signal. The converted digital signal enters FPGA chip for data processing. The high-speed FPGA chip is equivalent to the CPU of the computer, where the signal is processed A large number of calculation and processing, such as digital filter, calculation characteristic parameter, FFT calculation, spectrum parameter calculation, etc., are carried out for the No. 1 signal. The calculated data enters the communication main board through the main board slot, and then the data is integrated and transmitted to the computer through the communication chip of the main board via the USB 3.0 or the network interface of the communication card;

Picture Three: SAEU3H Module Network Card

The SAEU3H host is divided into two types: with network card and without network card. The difference is that the network card can make the data upload to the computer equipment through the network interface, but the network card needs to occupy a host slot, so that the main chassis maximum channels are reduced by 4 channels

When using the network card should pay attention to the follows:

1) The network card occupies one acquisition card slot, and can only use No. 1 slot.

2) After using the network card, the SAEU3-A chassis supports up to 4 cards and 16 channels, and the SAEU3-Bchassis supports up to 11 cards and 44 channels.

3) SAEU3H support USB3.0 and Ethernet two interfaces, but at the same time can only use one interface to connect with the PC;

4) The system default connection USB3.0 interface, if you need to use the Ethernet port, you must first disconnect the USB interface, and then connect the Ethernet interface;

5) When using the network card Ethernet interface to connect the PC, it is necessary to pay attention to establish the connection and identify the acquisition card takes some time, about 3 seconds / card;

6) USB3.0 port data bandwidth of not less than 300MB, Gigabit Ethernet port data bandwidth of not less than 80MB;

7) Network card indicator integrated in the RJ45 socket, which is defined with the standard card;

8) Please use the attached cable first, since the purchase of network cable, please select the above five categories above.
