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.

Well, thanks for that. Can't you afford real advertisements?

You'd be sorely disappointed with the SN ratio of the microvolt signals.

That's true. What about the benefits of getting rid of input gain settings?

Sure it avoids confusion. Quite why digital recorders don't write the attenuator settings into the header is beyond me.

However by and large I know what attenuator settings I need before I start recording.

Also we tend to calibrate each setup, so we know what our overall system gain is.
