Micro Button
The micro button provides easy and quick access to important functions of the
R&S
RTO. After a function has been assigned, pressing the micro button
remotely controls this specific function on the base unit. For example, Continuous
Run and AutoZero are commonly assigned to the micro button.
To assign a function to the micro button with the R&S RTO oscilloscope:
► "Vertical" menu > "Probe Setup" > "Ch" tab > "Micro button action"
For more details on the available functions and settings for the micro but-
ton, refer to the "User Manual" of the R&S oscilloscope.

Offset Compensation
The R&S
RT
‑
ZD10/20/30 features two offset compensation functions: a differen-
tial offset compensation and a common mode offset compensation. Each function
compensates a particular DC component of the input signal, even in front of the
active amplifier in the probe tip. For a definition of differential and common mode
input voltages, see
chapter 5, "Characteristics of Differential Probes"
2.3.1
Differential Offset
The differential offset compensation is often referred to as
offset compensation
.
The differential offset function can compensate a DC voltage applied between the
positive and the negative input socket. This is particularly helpful if a small single-
ended signal with a large DC offset is measured with a differential probe, for
example, with the negative input socket connected to ground. As the
R&S
RT
‑
ZD10/20/30 measures differential voltages, setting a differential offset
compensation is directly visible on the oscilloscope screen as a voltage offset of
the measured waveform.
