Key Features and Key Characteristics
Product Description
1 Product Description
1.1 Key Features and Key Characteristics
The R&S RT-ZM is a modular probe consisting of a probe amplifier and various
probe tip modules for different applications.
The R&S RT-ZM probe family features the MultiMode function which allows you
to switch between single-ended, differential and common mode measurements
without reconnecting or re-soldering the probe.
With different tip modules and tip cables, the R&S RT-ZM probe can be connected to a wide variety of devices under test (DUT) and is suitable for various measurement tasks.
Provided with special features such as the R&S ProbeMeter and the micro button,
the R&S RT-ZM is designed to meet tomorrow's challenges in probing.
The probe is equipped with theRohde & Schwarz probe interface. It can be connected to any Rohde & Schwarz instrument that is compatible with this interface.
When connected to the front panel, the probe is controlled by the oscilloscope's
software. Supported oscilloscopes are listed in the data sheet.
1.1.1 Key Characteristics
The key characteristics of the probe are the following:
MultiMode feature for differential, common mode and single-ended measurements
Two different probe gain settings with 10:1 and 2:1 attenuation to achieve low system noise
Bandwidth DC to 1.5 GHz (R&S RT-ZM15)
DC to 3 GHz (R&S RT-ZM30)
DC to 6 GHz (R&S RT-ZM60)
DC to 9 GHz (R&S RT-ZM90)
DC to 13 GHz (R&S RT-ZM130)
DC to 16 GHz (R&S RT-ZM160)
Dynamic range ±2.5 V (10:1 attenuation)
±0.5 V (2:1 attenuation)

1.1.2 Key Features
Micro button
The micro button at the probe head can remotely control different functions on the
base unit. The assigned function is configured via the base unit.
For details, see Chapter 2.5, "Micro Button", on page 18.
R&S ProbeMeter
The R&S ProbeMeter measures the DC voltage of the input signal directly at the
probe tip. It provides a continuous high-precision DC voltage measurement that is
independent of the settings of the oscilloscope and runs in parallel to the time
domain measurement. If activated on the base unit, the measured value is displayed on the screen of the Rohde & Schwarz oscilloscope.
The R&S ProbeMeter simultaneously measures both differential and common
mode DC voltages.
For details, see Chapter 2.7, "R&S ProbeMeter", on page 23.
Probe DC correction
The probe amplifier includes an integrated data memory with individually determined DC correction parameters (e.g. gain, offset). These correction parameters
are read out and processed by the Rohde & Schwarz oscilloscope. As a result,

Unpacking
the probe offers a very high degree of DC accuracy so that additional calibration
procedures are not required.
Probe frequency correction
The R&S RT-ZM probe amplifier includes an integrated data memory with individually measured S-parameters. These correction parameters are read out and processed by the Rohde & Schwarz oscilloscope. This leads to a more accurate
probe frequency response and an enhanced measurement accuracy.
1.2 Unpacking
The carrying case contains the following items:
●
R&S RT-ZM modular probe
●
Carrying case
●
Accessory boxes
●
User manual
●
R&S RT-ZM data sheet
●
Calibration certificate
●
Documentation of calibration values (if
ordered)
●
Foam inlay for tip cables
If R&S RT-ZMA tip modules were ordered, they come in a separate packaging
and can be inserted into the foam inlay.
1.2.1 Inspecting the Contents
●
Inspect the package for damage.
Keep the package and the cushioning material until the contents have been
checked for completeness and the device has been tested.
If the packaging material shows any signs of stress, notify the carrier and your
Rohde & Schwarz service center. Keep the package and cushioning material
for inspection.
●
Inspect the probe.

If there is any damage or defect, or if the R&S RT-ZM modular probe does not
operate properly, notify your Rohde & Schwarz service center.
●
Inspect the accessories.
If the contents are incomplete or damaged, notify your Rohde & Schwarz service center.

1.3 Description of the Probe
The probe consists of the active probe amplifier, the probe box for connection to
the oscilloscope, the probe cable and various probe tip modules.

and 0.6 mm to 0.8 mm (24 mil to 35mil) round
pins.
1.3.2 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 provides 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 generated 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.

1.3.3 Probe Tip Modules
To use the probe for measurements, select the appropriate probe tip module and
connect it to the probe amplifier.
Figure 1-2 shows all probe tip modules are available for the R&S RT-ZM probe.
The usage of probe tip modules is described in Chapter 3, "Connecting the Probe
to the DUT", on page 24.
