Sensor head
The sensor head clamps on the conductor being measured, and carries out the
actual current measurement. It is a precision assembly including a molded com-
ponent, a ferrite core, and a Hall effect element. It may be damaged if subjected
to sudden changes in ambient temperature, or mechanical strain or shock, and
therefore great care should be exercised in handling it.
Coarse adjustment trimmer
Use this only when adjustment is not possible within the range of the zero adjust-
ment. Use a nonconductive screwdriver (e.g. ceramic driver) for adjustment.

Probe Box
The probe box connects the probe and the oscilloscope via the Rohde
&
Schwarz
probe interface. The Rohde
&
Schwarz probe interface contains a male precision
7
mm (276
mil) BNC connector and six pogo pin connectors. This interface pro-
vides the required supply voltage and is also used to transmit analog signals and
digital data simultaneously. All the analog voltages required by the probe are gen-
erated in the probe box. This approach ensures that it will be possible to operate
future probes on any base unit that features a Rohde
&
Schwarz probe interface.

(2) Release knob
Connect the R&S
RT-ZC20B only to an instrument with Rohde
&
Schwarz probe
interface. Never connect it to a usual BNC jack. Although the 7
mm coaxial con-
nector looks like a standard BNC connector, it is constructed differently and does
not fit to the standard BNC jack. The interface of the R&S
RT-ZC20B can with-
stand a higher frequency limit.
