AE Cable and Specification

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;

SAEU3H Card specifications

The AE module is designed with 4 channels per card. Each channel has 10M, 16bit independent ADC, high speed FPGA chip signal processing, 1Gb DDR ram, to ensure that the data is not lost; unique hardware real-time digital filter, any Control signal bandwidth; SAEU3H acquisition technical specifications in Table 1-1:Table 1-1SAEU3Card technical specifications table：

Picture one SAEU3H Standard AE card

Picture two: SAEU3H External Parameter AE 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.

Chassis front panel

Chassis card description：The left side of the front panel of the chassis for the AE module slot, the left side of the slot can be inserted into the card or AE module, insert the network card can be achieved data transmission network; each card above a total of eight indicators, each channel has two, In the collection card specification section has been described, not repeat here；

The lower right corner of the panel set to set the chassis card card number of the initial settings for a number of chassis cascade situation, the card number set in front of all the cascade chassis AE module total T, the chassis AE module number from left to right The number starts incrementing from T + 1。

The status of the front panel indicators on the chassis is shown in Table 3 below：

Table 3 Chassis Front Panel Indicator Status Description

Chasis Rear Pannel

The rear panel of the chassis provides some interfaces, as follows:

Power supply: AC 100-240V / 50-60Hz;

Ground column: the use of the ground, the ground must be a good access to the earth;

Cascade: Chassis can be cascaded use, not connected to the main line is the main chassis. A system with and only one chassis as the main chassis;

USB port: USB3.0 interface, connected to the PC;

Card panel

The card is mainly with the external collection interface acquisition card, no external parameters of the acquisition card, network communication card, the panel structure as shown below：
