Identification of the Probe
When the probe is connected to the oscilloscope, the oscilloscope recognizes the
probe and reads out the probe-specific parameters.
The oscilloscope settings for attenuation and offset are automatically adjusted.
After the probe is connected to the oscilloscope and the settings are adjusted, the
waveform is shown for the channel to which the probe is connected.
The complete probe information is shown in the probe settings dialog. For more
information, refer to the user manual of your oscilloscope.

Using the Probe
2.3.1
Zero Adjustment
The zero error can impair the measurement results, therefore, correct the zero
error if necessary. The zero error of the probe itself is very small. However, differ-
ences in DUT and oscilloscope ground levels can cause larger zero errors visible
on the oscilloscope's screen. If the DUT is not floating but ground-referenced, an
zero adjustment improves the measurement results.
The zero error is corrected at the oscilloscope. Depending on the type of the used
oscilloscope, correction is done automatically using the AutoZero function, or
manually ("Zero Adjust" or similar setting). Refer to the oscilloscope's user man-
ual for available functionality and its usage.
1. Connect the probe to the Rohde
&
Schwarz oscilloscope.
2. Set the oscilloscope to the smallest vertical scale.
3. Short the signal pins and the ground pin together.
