1 For Your Safety
To prevent electric shock, personal injury, or fire caused by high voltages, carefully
read and observe the following safety information:
●This chapter, the first part of the safety booklet, provides warnings and safety infor-
mation for usage of oscilloscopes, probes, and other measurement accessories.
●The second part of the safety booklet provides basic safety instructions
●Product manuals provide specific safety instructions for procedures and measure-
ment accessories.
Electrical safety
●Voltages higher than 30 V RMS, or 42 V peak, or 60 V DC are regarded as hazard-
ous contact voltages. When working with hazardous contact voltages, use protec-
tive measures to preclude direct contact with the measurement setup:
– Do not touch exposed connections and components when power is applied.
– Use only insulated voltage probes, test leads and adapters.
●Make sure that only personnel familiar with the potential risks of measuring electri-
cal quantities controls the instrument. Observe applicable local or national safety
regulations and rules for the prevention of accidents.
●Use only specified probes and accessories that comply with the measurement cat-
egory (CAT) of your measurement task. If you use other than Rohde & Schwarz
accessories, make sure that they are suitable for the instrument and the measure-
ment task.
●Observe all voltage and current ratings of the instrument, the probes, and the
accessories. The lowest rated component defines the rating of the complete mea-
surement setup. Limits and ratings are marked on the products and listed in the
data sheets.
For probes, consider that the rated voltage depends on the frequency. The voltage
limitation curves are provided in the data sheet. Do not exceed these two ratings:
– Maximum measurement voltage from the probe tip to the probe reference lead.
– Maximum floating voltage from the probe reference lead to earth ground.
●Set the correct attenuation factor on the instrument according to the probe being
used. Otherwise, the measurement results do not reflect the actual voltage level,
and you might misjudge the actual risk.
●Set up all connections to the instrument before applying power.
●Do not open the instrument casing.
●Do not use the instrument if the instrument casing, the display or any probe or
accessory are damaged. If you detect or suspect any damage, have the instrument
or accessory inspected by qualified service personnel.
●Do not operate the instrument in wet, damp or explosive atmospheres. Make sure
that all connectors are completely dry before connecting the inputs.
●Observe the operating conditions specified in the data sheet and in the basic safety
instructions.

For Your Safety
R&S®Scope Rider RTH
8User Manual 1326.1578.02 ─ 12
Battery replacement
●Disconnect power supply, probes, test leads and all other cables before opening
the battery cover.
●Use only the specified Li-ion battery pack, which is delivered with the instrument.
You can order additional battery packs at Rohde & Schwarz, see data sheet for
order number.
●Do not operate the instrument with the battery cover open.
●Use only the specified power adapter, which is delivered with the instrument.
Cleaning
Remove all probes, leads, USB and LAN cables and power supply before cleaning the
instrument. Use only cleaning materials that are specified in the manual.
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.
●O - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for exam-
ple, 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.

2 Getting Started
2.1 Preface
2.1.1 Key Features
The R&S RTH is the perfect multi-purpose tool for the lab and in the field. Outstanding
key features are:
●Full isolation of all channels and interfaces
●CAT IV 600 V / CAT III 1000 V safety rating
●Bandwidth 60 MHz to 500 MHz with 5 GS/s sampling rate
●Acquisition speed up to 50.000 waveforms per second
●2 mV/div sensitivity
●Up to 200 V offset range
●33 automatic measurement functions
●Full operation using touch or keypad
●Wireless LAN and Ethernet for web based remote control and quick data access
(optional)
The R&S RTH combines:
●Lab performance oscilloscope
●Logic analyzer with 8 digital inputs (optional)
●Protocol analyzer with trigger and decode (optional)

2.1.2 Input Isolation
The instrument has independently floating isolated inputs. Each input channel has its
own signal input and its own reference input. Each input channel is electrically isolated
from the other input channels. Therefore, each reference of the used inputs must be
connected to a reference voltage. Furthermore, input channels are electrically isolated
from the communication ports and the power adapter input.

Figure 2-1: Isolation scheme of the R&S RTH
The input isolation has several advantages:
●You can measure independently floating signals simultaneously.
●The risk of causing a short circuit while measuring multiple signals is reduced sub-
stantially.
●When measuring signals with different grounds, the induced ground currents are
kept to a minimum.
