Safety information
1 Safety information
The product documentation helps you to use the product safely and efficiently.
Keep the product documentation nearby and offer it to other users.
Safety information warns you about the potential dangers and gives instructions
how to prevent personal injuries or damage caused by dangerous situations.
Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation.
Intended use
The equipment under test (EUT) is a signal quality test and development board,
indented to be used at laboratory or test and measurement areas. These areas
are used for analysis, testing and servicing and where equipment is operated by
trained personnel.
Operating site
Only use the product indoors, and keep it dry. The product has no casing and is
sensitive to moisture and humidity.
The product is suitable for pollution degree 2 environments where nonconductive
contamination can occur. For more information on environmental conditions such
as ambient temperature, see the specifications.
Installation
Make sure to connect only Ethernet devices with RJ-45 interface that are
designed according to IEEE802.3 10BASE-T, 100BASE-T/TX, 100BASE-T1,
1000BASE-T, or 10GBASE-T.
ESD and EMI impact
The product is sensitive to electrostatic discharge (ESD) because of open modules. Protect the work area against electrostatic discharge to avoid damage to
electronic components. Always work at a static-approved workstation.
Electromagnetic interference (EMI) can affect the measurement results. To avoid
any impact, use only USB cables shorter 3 m.

2 Product description
The R&S RT-ZF5 test fixture is a multipurpose fixture to probe or tap Ethernet signals up to the 10GBASE-T standard.
The fixture can be used to separate the directions of a full duplex connection for
decoding applications like R&S RTO/RTO6/RTP-K57 (100BASE-T1).
The R&S RT-ZF5 can also be used for compliance testing of energy-efficient
Ethernet (100BASE-TX and 1000BASE-T). For compliance testing, it is used in
combination with:
●
R&S RTO/RTO6/RTP oscilloscope
●
EEE: R&S RTO-K86 (1333.1992.02), R&S RTP-K86 (1337.8833.02): requires
R&S RTO/RTO6/RTP-K22
●
R&S ScopeSuite software
For data, see the "R&S RT-ZFxx Oscilloscope Test Fixtures - Specifications" at

2.2 Board description
The R&S RT-ZF5 Ethernet probing fixture has three labeled sections, which are
designed for specific test cases. You can cut the board at the section limits and
use each section as a separate board.
"Directional Probe" section
Separates the signals on a (differential) full duplex Ethernet connection (like
1000BASE-T or 100BASE-T1) into a forward signal and a backward signal. The
fixture supports all four Ethernet lanes in parallel. The couplers deliver -15 dB of
the original signal amplitude.
" Load and Probe" section
Terminates the signals with 100 Ω and offers pins for differential probing.
"DUT and Link Partner" section
Used to tap the connection between two Ethernet devices. It offers pins for differential and single-ended probes to ground probe connections.

3 Connecting the board
The appropriate DUT and probe connection depends on the test case. The
R&S ScopeSuite software provides a step-by-step guide that shows the required
setup for each test case.
The test preparation and measurements of the test cases are described in the
"R&S®RTO, R&S®RTP Ethernet Compliance Tests, Test Procedures Manual".
