An external attenuation can be set on the "Other" tab, see "External attenuation: Scale,
Attenuation" on page 163.
The shared probe settings are:
Type, Name, Bandwidth.............................................................................................. 166
Detect AutoZero, Use AutoZero..................................................................................166
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.
Remote command:
PROBe<m>:SETup:TYPE? on page 1207
PROBe<m>:SETup:NAME? on page 1207
PROBe<m>:SETup:BANDwidth? on page 1207
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.
