A dynamic signal analyzer achieved 130dB dynamic range. see: www.go-ci.com You may wonder, my sensor only has 60dB dynamic range. Why do I care about the 130dB dynamic range of your instrument? The real advantage of having a 130 dB dynamic-range is that the instrument can function without any input range settings. In traditional instruments, the input range settings, i.e., the amplifier gain, are where the operator can make the biggest mistakes. If you set the range too large, then you won't be able to measure small signals; if the range is too small, then the measurement may get overloaded. A handheld system will have more problems in such a setup. With the unique hardware design, the CoCo-80 reaches a 130 dB dynamic range. The instrument can measure signals as high as +/-10V or as small as a few micro-volts without concern of input range settings. Given this advantage, users don't need the range setting in the channel table. What do you think?
wonder what to do with 130 dB dynamic range?

That's dishonest. I'm very leery about dealing with a company that has demonstrated dishonesty toward potential customers.

He has no own food to grow. That's why he can only type in hundreds of messages every months in following the others while keep calling others dishonest.

Except for fertilizer merchants, I try to go with those who sling the least bullshit.

It reminds me of a customers spec I had to work with once. I had been written in Portuguese, then translated to Spanish, then translated to English. Neither of translators had tech background. I don't think anyone proof read the page - the display evidently has 7.5 colors ;>

Richard, Thanks for pointing it out. I value your critics because it will help us improving our products. Which reference page you are referring to? We did use technical writers edited most of documents.

Jerry, i'm still just giggling. it's kinda coincidental but some guy did something similar at sci.physics.research and his target was one of the guys sorta responsible for the newsgroup. i have to take a look at what others have said, but i felt the need to respond right away. r b-j
