The Prosig P8000 Auto-Zero function is used to remove the DC content of a signal.

For example, if you have a sine wave that is ±5 volts about 0 volts it has no DC offset. But if you have a sine wave with ±5 volt amplitude about 3 volts, then it has a 3 volt DC offset. Below is an example of these two sinewaves.

Two sine waves with and without DC offset

What Is The Difference Between Single Ended & Differential Inputs?

Prosig P8000 systems use differential inputs, but what are they and why are they so special? This subject is not always fully understood and, therefore, the focus of this article…
