Differential Probe 10 : 1
RT-Z D 0 8

800 MHz bandwidth

high input resistance of 200 kΩ

high dynamic range of ±15 V differential and ±30 V common

universal power supply using battery or USB cable

typical applications:
– differential signals like CAN Bus or LVDS
– DC-DC converter

General Information

The RT-ZD08 800 MHz Differential probe is best suited for measurements of high-speed differential
signals. These signals are commonly used in digital and power applications and especially at serial buses
like CAN. The RT-ZD08 can be powered by USB or battery and is compatible with all oscilloscopes with

50 Ω BNC inputs. Oscilloscopes without 50Ω input need a 50 Ω feed through BNC adapter.

The probe has a high input resistance of 200 kΩ combined with 1 pF input capacitance. This secures a
low loading of the device under test. The attenuation of the RT-ZD08 is 10 : 1.

Important hints

After unpacking please check for mechanical

dam a g e an d loose par t s o a t ing aro u n d in s ide the

instrument. In case of damage please inform the
transport company immediately. Do not operate
the instrument and protect it against unauthorized
operation.

Please consult the manual

Safety instructions

The instrument conforms to the European stan-

dards EN 61010-1 and IEC 61010-1, respectively.

Further Safety Informations

To avoid personal injury and to prevent re or

damage to this product or products connected
to it, review and comply with the following safety
precautions. Be aware that if you use this probe

as s e m b l y in a mann e r no t spe c i  e d th e prote cti o n

this product provides may be impaired.

– Only qualied personnel should use this

probe assembly.
– Use only grounded instruments.
– Connect the probe output to the measu-

rement instrument before connecting the

probe to the circuit under test. Disconnect

the probe inputs from the circuit under test

before disconnecting the probe from the

measurement instrument.
– Do not apply any electrical potential to the

probe input which exceeds the maximum

ratings of the probe.
– Keep away from live circuits.
– Avoid open circuitry. Do not touch con-

nections or components when power is

present.
– Do not operate with suspected failures.

– Repair only by qualied service personnel.

– Indoor use only.
– Do not operate in wet/damp environment.

Keep product surfaces dry and clean.
– Do not operate the product in an explosive

atmosphere.

Operating conditions

The permissible operating temperature is
+5 °C to +40 °C. During transport and storage the
temperature may be –20 °C to +70 °C. In case of
condensation after transport it is necessary to
dry the probe for at least 2 hrs. prior to operation.

Operate only in clean, dr y rooms.

Warranty and Repair

Our instruments are subject to stri ct qualit y con­trols. Prior to leaving the manufacturing site, each

instrument undergoes a 10-hour burn-in test. This
is fo l l o wed by ex te n s i v e func tional qual i t y te s t i n g

to examine all operating modes and to guarantee

comp l i a n c e wi t h th e spec i  e d tec hnic al data. The
testing is performed with test equipment that is

calibrated to national standards. The statutory
warranty provisions shall be governed by the laws
of the country in which the product was pur­chased. In c ase of any complaints, please contact
your supplier.

The product may only be opened by authorized

and qualied personnel. Prior to working on the

product or before the product is opened, it must
be disconnected from the AC supply network.
Otherwise, personnel will be exposed to the risk
of an electric shock.

Any adjustments, replacements of par ts, main­tenance and repair may be carried out only by

authorized technical personnel. Only original

parts may be used for replacing par ts relevant to
safety (e.g. power switches, power transformers,
fuses). A safety test must always be performed
after parts relevant to safety have been replaced
(visual inspection, PE conductor test, insulation
resistance measurement, leakage current mea­surement, functional test). This helps to ensure
the continued safety of the product.

Cleaning the Probe

Disconnect the probe and clean it with a soft
cloth. Make sure the probe is completely dry
before reconnecting it to an instrument. Avoid
using abrasive cleaners and chemicals containing
benzene or similar solvents.

Handling the Probe

Notes

Handle the probe with care and refer to the safety
notices in this manual. Note that the probe cable
is a sensitive part of the probe and, therefore, you
should be careful not to damage it through ex­cessive bending or pulling. You should also avoid
any mechanical shocks to this product in order to
guarantee accurate performance and protection.

Using the probe and accessories

To use the pr o b e , r s t slide open the ba t te r y com ­partment on the rear of the probe housing and
insert the 9 V battery. You can also use the USB
power cord that ships with the probe to supply
power instead of the batter y. Simply connect the
USB power cord to the probe and an USB port
(on a computer or oscilloscope).

Input for USB power cord

Battery Use

Insert one 9V battery in the back of the unit as
indicated within the chassis (see picture for the
battery location). When battery life has expired,
remove the battery. Note the WEEE label on the
battery and dispose it properly.

Then connect the BNC output connector to
the channel input of the oscilloscope. The os-

cilloscope must have a 50Ω input with ground

reference. In case the oscilloscope does not pro-

vide a 50Ω input please use a 50Ω feed through

termination.

Using the appropriate probe accessories, connect
the inputs to the circuit under test.

– To protect against elec trical shock, use only the ac-

cessories supplied with this probe or in the accessory
kit.

– This probe is made to carry out differential measure-

ments between two points on the circuit under test.
This probe is not made for electrically insulating the
circuit under test and the measuring instrument.
