1. Connect the R&S RT-ZHD probe to an R&S oscilloscope as described in Chap-
ter 2, "Putting into Operation", on page 20.
2.
Connect the safety alligator clip to the square wave output of the oscilloscope.
3.
Connect the other safety alligator clip to the probe ground connector of the
oscilloscope.
4. Press the PRESET and then the AUTOSET key on the oscilloscope.
5. Set the attenuation ratio on the probe to "Attenuation high" (e.g. 1500 V range).
A square wave with 1 V amplitude is displayed on the oscilloscope screen and
should not disappear if one of the following changes are made:
● The attenuation of the probe is manually set to "Attenuation low" (e.g. 150 V for
the R&S RT-ZHD15).
● The bandwidth limit of the probe is activated.
Interchange the safety alligator clips and redo step 4 and step 5.
Improve the displayed test signal
The high attenuation factor (e.g. 1000 with R&S RT-ZHD60) is responsible for high
noise on the relative low test signal. For stable triggering, it is convenient to narrow the
trigger bandwidth. Afterwards the noise of the signal could be reduced by averaging
(e.g. 20 waveforms).
