Using InfiniiMax Active Probes Offset
Notas de Aplicação
This application note explains how offset is applied in the Keysight InfiniiMax Active Probes and how to use offset for various applications. The purpose of offset in active probes or oscilloscope front ends is to allow the subtraction of most or all of the dc component of the input signal so the signal can better utilize the dynamic range of the input. A simplified diagram of how offset is applied for InfiniiMax probes is shown in Figure 1.
The three cases for types of signals and probe head types are:
- A single-ended probe head probing a single-ended signal
- A differential probe head probing a single-ended signal
- A differential probe head probing a differential signal
