FPGA Based real-time measurement and analysis  

What is an FPGA? An FPGA (field program

mable gate array) is a semiconductor device that includes designable logic elements and programmable internal circuitry. Designable logic elements can be programmed to replicate the functions of basic logic gates such as AND, OR, XOR, NOT, and more complex decoders or combinations of computational functions. 

Most FPGAs contain a simple flip-flop or a memory element with a more complete block of memory in a programmable logic element

(also known as an FPGA logical block). -Wikipedia.

Now See your Sound and Vibration!

SeeSV-S205 is a real-time sound camera which implements FPGA-based high-speed beamforming technology. It was developed for highly transient noise source detection, and also performs excellently on stationary noise sources. It is capable of capturing 25 images per second. Highly sensitive microphones detect small annoyance sounds immediately. Its major application is for Buzz, Squeak, and Rattle [BSR] noise source detection as well as Noise, Vibration, and Harshness [NVH] source visualization. The unique design of SeeSV-S205 makes accurately measuring sound easy. Now you can carry your sound camera anywhere to perform measurements. A Sound Camera has traditionally been heavy and expensive instruments. However, the SeeSV-S205 will open new doors and your ears. It has an ergonomic design, weighs only 

2 kg, and has a highly competitive price. Start your sound measurements with our new camera today.

Portable, Fast and Accurate!


SeeSV-S205 is based on the latest FPGA technology, which makes it possible to integrate signal conditioning, data acquisition, filtering, and beamforming processing into a single chip. Our FPGA is fast; it generates 25 sound images per second with

accurate resolution. Our single FPGA does not need high electrical power and is driven by Power of Ethernet [POE). 

Weighing a mere 2 kg, it is easily transportable and usable. MEMS microphone technology is improving every day and is achieving more than 56 dB signal-to-noise ratio. SeeSV-S205 uses highly accurate digital MEMS microphones for portable, fast, and accurate measurements 

what is FPGA?

A field-programmable gate array [FPGA] is an integrated circuit designed to be configured by a customer or a designer after manufacturing-hence "field-programmable" The FPGA configuration is generally specified using a hardware description language [HDL],similar to that used for an application-specific intergrated circuit [ASIC]   (www.wikipedia.org)

Improved performance  

In order to measure low frequency noises [50Hz~] with long wavelengths, our previous model had large spaces between microphones. Based on the idea that noises from industrial products such as BRS have relatively higher frequencies, we moved the measurement range [350Hz~], drastically reducing the size enough for mobile use.

 

Excellent usability

Its central handle at the back enables stable on-hand grip, allowing the user to control the noise source or computer with the other hand.

Two side handles enable the user to comfortably hold the camera in many different ways.

Two side handles also provide steady stand.

Easy Operation software

SeeSV-S205 includes simple, easy, and high performance software. It automatically starts their operation as soon as the user runs the software. You can record sound videos with our intuitive graphical user interface. 'Record' and 'Stop' buttons control video recordings and our ‘Replay’ button replays the recorded video at various speeds of your choosing. It is almost as simple as using an mp3 player. There are three knobs on the right side: 'Threshold', 'Image Range' and 'Image Average.' These make controlling the quality of your image simple.
