1 Safety and Regulatory Information
The product documentation helps you use the R&S RT-ZP03S safely and effi-
ciently. Follow the instructions provided here and throughout the manual.
Use the product only for its intended use and within its performance limits. If the
probe assembly is used in a manner not specified by the manufacturer, the pro-
tection provided by it may be impaired.
Operating site
Only use the product indoors, and keep it dry. The product has no casing and is
sensitive to moisture and humidity.
Do not use the probe in explosive atmospheres.
The product is suitable for pollution degree 2 environments where nonconductive
contamination can occur. Occasionally a temporary conductivity that is caused by
condensation must be expected. Temporary condensation occurs only when the
product is out of service.
Using the probe
Take the following measures for your safety:
●Before connecting the probe to a circuit under test, make sure the probe is
connected to a grounded measurement instrument.
●Do not connect a probe to any voltage that exceeds the maximum permissible
input voltage specified in the data sheet.
●Do not use the probe for measurements on mains circuit.
●Do not use the probes in circuits with measurement category II, III or IV.
●With increasing frequency the voltage on the probe tip should not be higher
than illustrated in the derating curve.
●Always connect the probe lead to earth ground.
Declaration of Conformity
The manufacturer declares the conformity of this product with the actual required
safety standards in accordance with the Low Voltage Directive IEC 61010-031
Safety requirements for electrical equipment for measurement, control and labo-
ratory use.

Measurement Categories
IEC 61010-2-030 defines measurement categories that rate instruments on their
ability to resist short transient overvoltages that occur in addition to the working
voltage. Use the measurement instrument and accessories only in electrical envi-
ronments for which they are rated.
●0 - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for
example, electronics, circuits powered by batteries, and specially protected
secondary circuits. This measurement category is also known as CAT I.
●CAT II:
For measurements performed on circuits directly connected to the low-voltage
installation by a standard socket outlet, for example, household appliances
and portable tools.
●CAT III:
For measurements performed in the building installation, such as junction
boxes, circuit breakers, distribution boards, and equipment with permanent
connection to the fixed installation.
●CAT IV:
For measurements performed at the source of the low-voltage installation,
such as electricity meters and primary overcurrent protection devices.
Disposal
This electronic product is classified within the WEEE/ RoHS category list as
monitoring and control equipment (category 9). Category 9 products are
exempted from the restrictions under the scope of the RoHS directive.
Rohde & Schwarz has developed a disposal concept for the ecofriendly disposal
or recycling of waste material. Rohde & Schwarz fully assumes its obligation as a
producer to take back and dispose of electrical and electronic waste. Contact
your local service representative to dispose of the product.

3 Adjustment
The probe can be adjusted for low (LF) and high frequency compensation (HF).
Figure 3-1: Compensation trimmer
LF adjustment
1. Connect the probe to a 1 kHz square wave signal.
2. Adjust LF compensation trimmer T1 for optimum square wave response.
Figure 3-2: LF adjustment with 1 kHz signal
RF adjustment
For special measurement tasks, an RF adjustment of the probe can be neces-
sary. Therefore, the probe has two adjustable trimmers below the label beside T1.
Remove the label if you need RF adjustment.

Adjustment
R&S®RT-ZP03S
9User Manual 1802.9573.02 ─ 03
Use the probe adjust output on the oscilloscope or a pulse generator (less than
1 ns rise time) for full bandwidth adjustment.
1. Make sure that the trimmers T2 and T3 are in a center position.
2. Set the timebase of the oscilloscope to 5 ns/div.
3. Start the RF adjustment with trimmer T3. Turn it until the peak of the adjusta-
ble pulse response reaches the end level without any overshoot.
4. Turn trimmer T2 in the same way, but accept a small overshoot for the first
few nanoseconds.

After adjustment, we recommend sticking the label again to avoid confusion of the
trimmers.
