SL-889 HDMI 2.1 Cat-3 Cable EMI Tester

User Guide

1. Overview

The SL-889 HDMI 2.1 Cat-3 Cable EMI Tester is designed for radiated emissions testing of HDMI 2.1 Ultra High Speed

cables and is compliant to the latest High Definition Multimedia Interface (HDMI®) 2.1 specifications.

This User Guide provides details on how to setup and test cables for radiated emissions for compliance in a EMI

chamber to HDMI 2.1 specifications.

For the latest updates to documentation or software updates, see online at:

SL-889 Hardware

Figure 1.1, Figure 1.2, and Figure 1.3 show the top view, the front panel view, and the rear panel view of the SL-889,

respectively.

1.1.1. Signal Path

Figure 1.3 shows the internal and external signal path of the SL-889. An internal Video Generator generates an ITU-R

BT-1729 test pattern which is fed to an HDMI transmitter. When an external HDMI cable DUT is connected, the Tx will

begin transmitting a HDMI 2.1 Video/Audio data stream to the built-in HDMI receiver. At this point the Test Equipment

can be used inside an RF chamber, and radiated emissions scans may be taken. An optional LCD monitor can be used

during Pre-Scan operations to visually verify the signal has been successfully received across the DUT cable.

1.5.1. 12V Power Supply

The included 12V power supply has been chosen for proper operation with the SL-889. It has been modified with the

addition of a ferrite filter for lower noise operation. Please do not substitute another supply as the results of EMI scans

cannot be guaranteed.

Figure 1.7. 12V Power Supply

1.5.2. 2M Golden Test HDMI Cat-3 Cable

The included 2M cable has been developed for specific use with the SL-889. It has been shown to have superior RF

suppression. It should be kept as a test reference cable and can be used to calibrate your SL-889 to different RF

chambers.

2. The SL-889 in Standard Test Mode

In its standard test configuration, the SL-889 offers audio and video test features to enable radiated emissions

compliance testing to HDMI 2.1 specifications.

These are the operations that are available in the standard test mode:

1. Generate a calibrated HDMI 2.1 signal output using the HDMI OUT1 port

2. Receive a HDMI 2.1 signal using the HDMI IN1 port

Calibrated HDMI 2.1 Tx Output Notes:

The SL-889 generates fixed stimulus to an HDMI 2.1 Category 3 Cable so the DUT cable’s EMC

Emission performance can be measured.

The SL-889 does not go through HDMI 2.1 FRL Link Training, and does not adjust the TX signal in

response to the RX’s measured error rate.

The documentation shipped with each SL-889 contains waveforms captured while it was sending

TMDS data at 2.97 GHz and FRL data at 12.0 GBPS.

A waveform exhibiting a Rising/Falling/Rising pattern (or a Falling/Rising/Falling pattern), with the

time between the first and last edges at a minimum, represents 2 bit times.

The included 12.0 GHz waveform was captured at 200 Picoseconds (ps) per division, with each

division internally subdivided by four tick marks.

Each 1/5th of a division is 40 ps.

A 12.5 GBPS signal would result in a bit time of 80 ps.

In the faster waveform the time between the first and last edges of the Rising/Falling/Rising

pattern is slightly more than 4 tick marks (160 ps).

One bit time is half the total time, or slightly more than 80 pS.
