The shared probe settings are:
Type, Name, Bandwidth..............................................................................................195
Detect AutoZero, Use AutoZero..................................................................................195
External attenuation: Scale, Attenuation.....................................................................196
Type, Name, Bandwidth
The fields show the characteristics of a recognized or predefined probe for information.
If the instrument cannot recognize the probe, and the probe is not known, the "Type" is
"None", and the other fields are empty.

Detect AutoZero, Use AutoZero
Differences in DUT and oscilloscope ground levels can cause larger zero errors, which
affect the waveform. If the DUT is ground-referenced, the AutoZero function corrects
the zero error of the probe to optimize measurement results at small signal levels. The
validation limit depends on the probe attenuation because probes with high attenuation
often have to compensate high offsets. AutoZero detects offset values even when the
signal is out of the current measurement range.
To correct the zero error of voltage probes, short the signal pin and the ground pin
together and connect them to the ground of the DUT. Then tap "Detect AutoZero".
While the alignment is running, the instrument switches to DC coupling to display the
waveform correctly.
