I'm really confused understanding the following device manual:https://www.endevco.com/product/prodpdf/136.pdf I don't understand most of what they write. Any one has some idea about these terminology?
Input impedance: 1 Meg Ohm minimum. Is that the built-in input impedance of the amplifier? If it is why doesn't it just say 1 Meg Ohm? Why does it say "minimum"?
What does "Common Mode" mean in this context? Isn't' it supposed to be very small for amplifiers? It says 50 Volt. Why do I have to know that?
Common Mode Rejection: It says 200 ohm imbalance, DC to 60 kHz. I don't understand what they mean.
Input imbalance adjustment: Whats that about? Do I supposed to deal with it?
Linear output: What is the difference between linear output and output?
Corner frequency? Is that a kind of limitation?
Cross talk between channels? 80 db RTI. What does it mean?
8 ) Resolution? Do they mean the amplification factor for the signal input?
