ROHDE SCHWARZ RT-ZP03S R&S Passive Probe
Safety and regulatory information
The product documentation helps you use the R&S RT-ZP03S safely and
efficiently. 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 protection 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:
- If any part of the product is damaged or broken, stop using the product. Check the probe cable regularly for wear. Touching a worn cable during measurements can cause injuries.
- Before connecting the probe to a circuit under test, make sure that 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 datasheet.
- Do not use the probe for measurements on main circuit.
- The probe is not rated for any measurement category. Do not use the probes in circuits with measurement categories 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 laboratory use. Part 031: Safety requirements for hand-held probe
assemblies for electrical measurement and test
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 environments for which they are rated.
-
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 a 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.

Adjustment
The probe can be adjusted for low (LF) and high-frequency compensation (HF).
LF adjustment
- Connect the probe to a 1 kHz square wave signal.
- Adjust LF compensation trimmer T1 for optimum square wave response.
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.
Compensation trimmers for RF adjustment
Use the probe adjust output on the oscilloscope or a pulse generator (less than 1 ns rise time) for full bandwidth adjustment.
- Make sure that the trimmers T2 and T3 are in a center position.
- Set the time base of the oscilloscope to 5 ns/div.
- Start the RF adjustment with trimmer T3. Turn it until the peak of the adjustable pulse response reaches the end level without any overshoot.
- Turn trimmer T2 in the same way, but accept a small overshoot for the first few nanoseconds.
RF adjustment: compensation times for both trimmers
After adjustment, we recommend sticking the label again to avoid confusion of
the trimmers.
Maintenance
Cleaning
- Clean the outside of the product using a soft cloth moistened with either distill-led water or isopropyl alcohol. Keep in mind that the casing is not waterproof. Note: Do not use cleaning agents. Solvents (thinners, acetone), acids, and bases can damage the labeling or plastic parts.
- Dry the product completely before using it.
